SkypeSDK Video and audio issue - mediaRelayAccessToken not found - skype

I'm having problems with adding an audio or a video service to a coversation.
The chat service works fine for me.
When I add a video or an audio service I get following error:
Error: GET /ucwa/oauth/v1/applications/113925534802/communication/mediaRelayAccessToken failed: 404

The Skype For Business Plugin is installed and works fine.
A Skype Edge server is currently not installed.
I'm using Internet Explorer 11.
The error occurs with the Skype Web SDK On Prem Sample from Microsoft as well as on my own website.
When I try to add video or audio for the second time to the same conversation i dont get any error message at all, but it still doesn't work. The request doesnt show up in the dev tools nor in fiddler. I'm using the latest version of the Skype SDk bootstrapper.
Both clients and server are in the same subnet.
Thanks in advance.

I encountered the same problem. Not sure how it happens, but the sdk has troubles to fetch or apply the media config.
You can use the this workaround:
Following line 18,892 in the debug version of the sdk, comment out both calls:
uninit();
throw error;
in the function init() of the section MediaConfig. Resulting in:
function init() {
pcMediaConfig = mediaPlugin.createComponent({
type: 'MediaPlatformConfig',
hide: true,
inproc: false
});
pcMediaConfig.event(onPluginComponentEvent);
pcMediaConfig.state.changed(function (state) {
log('pcMediaConfig.state = ' + state);
});
var p = pcMediaConfig.load().then(getMediaConfig).then(setMediaConfig).then(null, function (error) {
log('MediaConfig::init rejected');
//uninit();
//throw error;
});
return p;
}
Therefore you have to download the bootstrapper and the sdk to permanently apply the patch. To do this just fetch both in the debug version (bootstrapper version 1.2.5) and replace in function onConfig(config) line 48
}, config.corsScript && (scriptAttributes.crossOrigin = ""), loader.loadScript(getPackageUrl(config), null, handleError, scriptAttributes);
with
}, config.corsScript && (scriptAttributes.crossOrigin = ""), loader.loadScript("./scripts/SkypeSDK.js", null, handleError, scriptAttributes);
or your equivalent path

This is currently a limitation of the Skype Web SDK: it has a dependency on the mediaRelayAccessToken to proceed with audio/video calls. The dev team is aware of this issue and it may be fixed in a future release of Skype Web SDK.
The hacky way recommended above is basically to allow the SDK to continue the call upon missing mediaRelayAccessToken, so it may let you bypass the issue.
The media relay access token is returned by an edge server, so you may also try to deploy an edge server to work around this issue.

Unable to start Next 13 app directory (beta) in production mode

Step 1: Automatically create a new Next.js project using the new beta app directory:
npx create-next-app#latest --experimental-app
pages/api/hello.ts
// Next.js API route support: https://nextjs.org/docs/api-routes/introduction
import type { NextApiRequest, NextApiResponse } from 'next'
type Data = {
name: string
}
export default function handler(
req: NextApiRequest,
res: NextApiResponse<Data>
) {
res.status(200).json({ name: 'John Doe' })
}
This file is identical to the one created automatically created by npx - there are no modifications.
I am trying to build a simple home page, which fetches data from the api which gets data from my database. Either way an await/async will be required. I am following the instructions from here.
In this example I will demonstrate that even awaiting the supplied hello api can't seem to run in production, and I can't work out why.
app/page.tsx
async function getHelloAsync() {
const res = await fetch('http://localhost:3000/api/hello', { cache: 'no-store' });
// The return value is *not* serialized
// You can return Date, Map, Set, etc.
// Recommendation: handle errors
if (!res.ok) {
// This will activate the closest `error.js` Error Boundary
throw new Error('Failed to fetch data');
}
return res.json();
}
export default async function Page() {
const hello = await getHelloAsync();
return (
<main>
<h1>Hello: {hello.name}</h1>
</main>
)
}
To test the hello api works, I confirm that running pn run dev and then curl http://localhost:3000/api/hello the following successful response is received:
{"name":"John Doe"}
Next up we exit the dev server and run:
pn run build
The first headache is that the build will completely fail to build unless one adds { cache: 'no-store' } to the fetch command:
const res = await fetch('http://localhost:3000/api/hello', { cache: 'no-store' });
or adds this to the top of app/page.tsx:
export const fetchCache = 'force-no-store';
I am actually not sure how one would even build this if you wanted to cache the response or use revalidate instead and provide an initial optimistic response, because without cache: no-store it refuses to build outright. Ideally instead it should just cache the result from /api/hello and not fail. Running the dev server at the same idea as doing the build does allow the build to work, but then as soon as you exit the dev server and run pn run start then all the api calls fail anyway. So that is not a good idea.
This leads us to the next problem - why are the api calls not working in production (i.e. when calling pn run start).
Step 2:
pn run build
pn run start
Confirm that the following still works and yes it does:
curl http://localhost:3000/api/hello
Result:
{"name":"John Doe"}
Now we visit http://localhost:3000 in a browser but, surprise! We get the following error:
> next start

}
Why is it saying that the connection is refused when we know the API is available? I can't get this to run at all. I know this is beta but surely the code should actually run right? How do I make this code work?
Also if anyone knows where where the logs are that I'm supposed to be accessing to see digest '3567993178' please let me know.

Why do I get a "502 Gateway" error from NextJs app hosted on Firebase for POST requests only?

I started to build an API using NextJs framework. I want it to be hosted on Firebase (Hosting and Functions). Everything is working as long as I send only GET requests. When I send a POST request I receive a "502 Bad Gateway" error.
It's very simple to reproduce. You just have to download and deploy the example provided by the team developing NextJs.
create a new project on Firebase console
install the "with Firebase hosting" example
change the project name in the .firebaserc (line 3) file
create a folder "api" under the folder "pages"
create a file "hello.js" under the folder "api" and add the following snippet
export default async (req, res) => {
const {
body,
method
} = req;
console.log("method :>> ", method);
console.log("body :>> ", body);
switch (method) {
case "POST":
res.status(200).end(`Method ${method} supported!`);
break;
default:
res.setHeader("Allow", ["POST"]);
res.status(405).end(`Method ${method} Not Allowed`);
}
};
deploy the app
send a GET request to "https://[project-name].web.app/api/hello" and see it works
send a POST request to "https://[project-name].web.app/api/hello" and see it does not work
Do you have a the same error as me?
I spent 2 days to read articles, watch videos and try different configurations. You can even update the firebaseFunctions to add a console.log and see the POST request is caught by the Firebase Cloud Function but the NextJs server does not pass it to our API like it does for a GET request. It's out of my skills range...
Below the output you should have. The POST request should be answered with 200 - Method POST is supported!.
This was a real pain to track down, but after poking around myself for a while, I found that the same issue crops up for PUT and PATCH requests. Which suggested that it had something to do with the body of the request. Annoyingly, after finding that out, I stumbled across the thread of Issue #7960, where they found the same problem.
Simply put, the body of the request processed once by https.onRequest() and then nextjsHandle() tries to parse it again. Because the body was handled already, the raw-body module (within nextjsHandle()) waits indefinitely for 'data' events that will never come.
Currently, there isn't a way to turn off the body parsing done by https.onRequest(), so it must be disabled on the next.js end. Unfortunately, there isn't a global off switch for body parsing that can be added in next.config.js and it must be done for each and every API route (the files in pages/api) (which may change if the proposed fix in PR #16169 is added).
To disable body parsing for a given route, you add the following to the route's file
export const config = {
api: {
// disables call to body parsing module
bodyParser: false,
}
};
However, as mentioned in Issue #7960 by #rscotten, you might also want to use next dev while developing your app, so you need to enable it while using next dev but disable it while deployed. This can be done using
export const config = {
api: {
// disables call to body parsing module while deployed
bodyParser: process.env.NODE_ENV !== 'production',
}
};
Applying these changes to hello.js gives:
export default async (req, res) => {
const {
body,
method
} = req;
console.log("method :>> ", method);
console.log("body :>> ", body);
switch (method) {
case "POST":
res.status(200).end(`Method ${method} supported!`);
break;
default:
res.setHeader("Allow", ["POST"]);
res.status(405).end(`Method ${method} Not Allowed`);
}
};
export const config = {
api: {
// disable nextjs's body parser while deployed
// (as body parsing is handled by `https.onRequest()`),
// but enable it for local development using `next dev`
bodyParser: process.env.NODE_ENV !== 'production',
}
};

Unknown http error with http request to an iis server with ionic

I've got a problem with my ionic app. I try to get a json object from my iis (asp.NET) server. But the request doesn't even come into my controller. Everytime, i get the same error:
http failure response for (unknown url) 0 unknown error
At first, I thought it was just a cors problem so i fixed it but now, it works with chrome and internet explorer 11 but not with edge and, more important, it doesn't work on device.
I don't think the problem is with my typescript code since there is no problem with a Google request... But, just in case, there is my code:
this.http.get('http://localhost:60196', {withCredentials : true}).subscribe(data => {
this.testData = JSON.stringify(data);
}, err => {
this.testData = JSON.stringify(err);
});
For the record: my iis server use windows impersonation and my app must run on windows devices (i didn't try my code with android or ios devices).
Thank you very much.
it doesn't work on device
this.http.get('http://localhost:60196', {withCredentials : true}).subscribe(data => {
this.testData = JSON.stringify(data);
}, err => {
this.testData = JSON.stringify(err);
});
Get request is rerencing to localhost. Here should be some Api endpoint when testing it on device...

SignalR: getting error: WebSocket closed

I am working on project of Ionic with angular and AspNet with SignalR that have chat module.
I use SignalR for Chat.It's working smoothly but some time i am getting error as per below screen shot and because of that it's get stop working at all.
I have hosted my service on IIS and creating proxy and communicating with client and server. Here is sample
(function () {
angular
.module('app')
.factory('SignalRFactory', SignalRFactory);
SignalRFactory.$inject = ['$rootScope', 'Hub', 'ionicToast'];
function SignalRFactory($rootScope, Hub, ionicToast) {
var signalRLocal = this;
var serverURL = 'https://serivcerURL.com/signalr';
//Hub setup
var hub = new Hub('CommunicationHub', {
rootPath: serverURL,
listeners: {
'send': function (data) {
console.log("send " + data);
}
},
errorHandler: function (error) {
//Here i am getting that websocket closed error
console.error(error);
}
});
signalRLocal.Connect = function (user) {
console.log("SignalR Connecting as :" + user.UserName);
hub.invoke('connect', user);
};
return signalRLocal;
}
})();
I have hosted service on IIS. I search for the solution and find something like this link
I also try with above link solution by using "long Polling" as per below
Hub.connection.start({ transport: 'longPolling' });
But i don't want to use "long Polling" at all.
So can someone help me to figure out this issue without use of 'long Polling'.
Can someone tell me what configuration i have to do at client side or at IIS level.
As we said in comments, SignalR client will try to reconnect after the connection is lost. Besides, many factors (such as physical network interruption, client browser failure, server offline etc) can cause the connection lost, this article explains some disconnection scenarios, you can refer to it and find the possible causes of the issue.
Besides, as I mentioned in comment, you can call the Start method from your Closed event handler (disconnected event handler on JavaScript clients) to start a new connection to make client automatically re-establish a connection after it has been lost.
edit:
The connection to ws://localhost:3156/signalr/signalr/connect?transport=webSoc‌​kets&clientProtocol=‌​1.5&connectionToken=‌​g8vpRv9ncVDjPIYB9UuE‌​pAAILEaOcTMTG9p46IA2‌​4 was interrupted while the page was loading.
Under "Client disconnection scenarios" section in the article, you can find:
In a browser client, the SignalR client code that maintains a SignalR connection runs in the JavaScript context of a web page. That's why the SignalR connection has to end when you navigate from one page to another, and that's why you have multiple connections with multiple connection IDs if you connect from multiple browser windows or tabs. When the user closes a browser window or tab, or navigates to a new page or refreshes the page, the SignalR connection immediately ends because SignalR client code handles that browser event for you and calls the Stop method.
I am trying same and my client is in vue.js. I have changed below in vue.config.js
module.exports = {
devServer: {
proxy: {
'/hub': {
target: 'https://localhost:5001',
changeOrigin: false,
secure: false,
headers: {
'x-forwarded-proto': 'http',
},
},
},
},
}
Previously i am trying 'x-forwarded-proto': 'https', when I changed to http its work.
https://localhost:5001 is my .net endpoint and http://localhost:8080 is my vue enpoint
Changed in Startup.csbelow,
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
endpoints.MapHub<CardsHub>("/hub/cardsHub");
});
Added below code in vue component
this.connection = new signalR.HubConnectionBuilder()
.withUrl('/hub/cardsHub')
.build()
In my case the culprit was the wrong version of Microsoft.AspNetCore.SignalR.Common
the default one installed was 5.0.3
but I was targeting 3.1.0
Downgrading to 3.1.12 fixed the issue with the connection.

Error while taking pictures using MeteorCamera.getPicture() while testing on a laptop

I am working to add a photo ability to my app using Meteor's mdg:camera plugin. For now, I don't have any PhoneGap devices setup, so I am testing on my laptop. I thought I read somewhere that the Meteor implementation would fall-back and use a simple file dialog when a camera wasn't available, but when I try to run the following code on my laptop:
var cameraOptions = {
width: 800,
height: 600
};
MeteorCamera.getPicture(cameraOptions, function (err, data) {
if (err) {
console.log(err);
// TODO Need to handle the error
} else {
if (!this.photos) {
this.photos = [];
}
this.photos.push({ submitted_by: Meteor.userId(), submitted_on: new Date(), photo_data: data});
}
});
I get the error:
Meteor.makeErrorType.errorClass {error: "unknownError", reason: "There was an error while accessing the camera.", details: undefined, message: "There was an error while accessing the camera. [unknownError]", errorType: "Meteor.Error"…}
I would actually like for users to be able to upload photos via the same button when using a laptop. For what it's worth, I actually do have a camera built-in, and I am developing on a 15" MacBook Pro.
On browser client, the mdg:camera falls back on using navigator.getUserMedia to try to obtain a video stream from the webcam, it does not allow the user to upload a photo.
https://github.com/meteor/mobile-packages/blob/master/packages/mdg:camera/photo-browser.js#L41
Unfortunately as we are speaking getUserMedia lacks support on Safari, which is probably the browser you are using working on a MacBook.
http://caniuse.com/#feat=stream
Try your application on Google Chrome or Firefox instead.
