On localhost, the app works just fine.
On EC2, the app runs behind nginx. It loads into the browser, but nothing shows up. The browser console displays an Error
TypeError: 'undefined' is not an object (evaluating 'Package["service-configuration"].ServiceConfiguration')
I have no idea how to tackle this problem. Any help appreciated.
EDIT
NGINX is not the problem. The same behavior if I access meteor server directly.
Running "meteor add service-configuration" does fix the above mentioned error, but the absence of the error does not fix the observed behavior, that the app does not render on EC2 whereas it does render when started on localhost. (The error message was the only visible difference between EC2 and localhost. So I suspected that would be the cause. Now that hypothesis must be wrong.) So the problem still persists.
Problem Solved. The Lesson:
Meteor has a debug mode and a production mode. The two may behave differently. On localhost, meteor runs in debug mode per default. On deploy to meteor.com or per mup, the default is production mode. To run meteor in production mode on localhost, run meteor --production.
It looks like you're trying to access the service-configuration configs on your browser.
These are not available client side. This also affects your localhost app but it doesn't break your app (doesn't give you a blank page) because meteor is in debug mode.
In debug mode Meteor files are not concatenated so an error like this would go unnoticed, even if it is thrown on your js console. In production mode the error would halt the rest of your script (since everything is concatenated into a single file)
You need to ensure the code that is doing this only runs on the server side. In general it's not a good idea to have access to the service configuration data on the client side.
Looks like Arunoda and crew are adding a buildOptions.debug setting to the next version of MUP, which should allow you to deploy via MUP and have it act like it's running on localhost. See Arunoda's answer to a related question and (at least for now) documentation for the development version of MUP.

I'm having trouble with setting up ACORE API's and then having them work on a website.
Background:
Azerothcore running 3.3.5 on a debian standalone server, this has the Database, Core files and runs both the world and auth server basically a standard setup that is shown in the how-to wiki.
I also have a standalone web server, on the same subnet, but it's a separate server running linux and normal web server stuff, this has a wordpress installation with azerothcore plugin for user signup etc.
I'm trying to add the player map (https://github.com/azerothcore/playermap) and the ACORE-API set of functions (server status, arenastats, BG que and wow statistics) (https://github.com/azerothcore/acore-api)
Problem:
I understand the acore-api must be run in a container (docker or whatever) on the server, which I have done and it binds to port 3000, I can then go to the local ip:3000 and it brings up this error. (all db's etc are connecting and soap is working)
error 404 when navigating to IP:3000
I do get a few errors when running NPM install seen here: I'm not sure if they would be causing any issues or not.
screenshot of NPM errors on install
But further that, when I put say 'serverstatus' on the webserver (separate server) and configure the config.ts file I can't seem to get anything to display.
I'm not sure what I'm doing wrong but is the same scenario for all of the different functions for the acore-api
How are these meant to be installed and function? I feel I'm missing a vital step.
Likewise, with PLAYERMAP I have edited the comm_conf.php and set the realmd_id, but when loading the page, I do get the map, but the uptime is missing and no players are shown?
Could someone assist if possible?
Seems like an issue with NodeJS version. Update your NodeJS to latest LTS version 16.13.0 (https://nodejs.org)
I have an API in a .NET project that I'm running with Visual Studio Mac (8.4.3). I run it in release mode, and it opens a browser window with localhost:5000. The browser window says "ok". However, when I try to hit endpoints in that API, it fails very quickly. When I ran this API (ie. same code) from another server and accessed it via proxy, it ran fine. For example, when I ran it on a server whose IP was 162.250.198.98 and proxied into it, I would hit an endpoint like 162.250.198.98:3000/api/user and it would work, but now when I try to run localhost:5000/api/user, either from my app or from Postman, it fails almost instantaneously. When running it in Postman, I tried what it suggested by turning off 'SSL certificate verification' in Settings, but no change.
Can anyone advise me on how to approach troubleshooting this?
Wait, so You are saying that while trying to call API on 162.250.198.98:3000/api/user You are fine but while trying to do the same thing on localhost:5000/api/user You are getting an error? Would it might be possible You have Your API configured to receive calls at 3000? :)?
No, but really - please chech it out, maybe it is that simple, I'm couting on it :).
You can change/check it in Visual Studio: main project > Properties > Debug > App URL.
I have a strange issue. I build my Meteor app and run it on android device using -
meteor run android-device --mobile-server=<my_aws_ip>:3000
When the app deploys immediately it connects to the server (and my javascripts etc works). After a few seconds, the page refreshs and none of the javascript callbacks work. Please help me debug this issue.
More information: If I change the client (and not the server), and deploy it, for the first few seconds, the changed client gets shown on the phone. After the first few seconds, the version which is present on the server is shown. So I think Cordova or Meteor is trying to fetch the client code from the server, which is breaking the app. Is there a way to prevent this behavior?
Even more data points -
My aws code does NOT have android and ios platforms installed. Because of this, I think the cordova plugins are not installed, causing a JS break somewhere.
Easiest fix I can think of is remove cordova autoupdate. This is being added by meteor-platform package. If I clone meteor-platform and comment out the cordova autoupdate, the app doesn't load.
Is there another way of removing autoupdate?
This sounds like you have a different version of your app deployed at the mobile-server address.
The local code is run in development mode. Your AWS one is likely in production mode (and may contain a syntax error).
When you run your app it sees the code is different and fetches the new/old (different) version with a hot code reload - hence the page refresh/flash.
To fix this, you need to find the syntax error in your code. It's best to view the ADB logger or run with meteor run --verbose android-device ....
This will provide a bit more information such as an Uncaught exception: cannot read .. of null error type error.
It's hard to say what the error is. The error prevents the rest of your code from executing. In production mode the entire project is one JS file. If there is an error of any kind half way along the file, the rest of the file will not execute.
Also, try loading <my_aws_ip>:3000 in your browser and watch for JS errors in the JS console.
You can also run it locally with --production to simulate a production build environment locally.
Enabling autoupdate but without a page refresh:
Reload._reload = function (options) {
console.log("Next load will load new version");
};
Recently I added email sending capability to my Meteor app, using both the email package, and the account registration APIs to send emails. The other day, after having tested this thoroughly on my dev machine, I deployed it to our production server using Meteor Up. Once deployed, I did a quick check that the email APIs were working properly, and let it be. A day or two later, I made some minor changes, wrapping these email APIs in a Meteor.defer method to speed up the UI. I tested the changes locally (all fine), and re-deployed. I also ran apt-get update on my server after seeing a notification there were some new security updates available. After doing this, the email system no longer works. I tried reverting back to my previous configuration, and it still isn't working. I'm getting a timeout error:
Exception while invoking method 'forgotPassword' Error: connect ETIMEDOUT
I was wondering if anyone had any ideas on what might be causing this timeout (a blocked port?...how can I diagnose this?). Given my SMTP port is working on my development machine, it doesn't seem to be an issue with my code, but rather either with the MUP deployment, or Ubuntu configuration. I'm not super familiar with configuring Ubuntu servers. Any suggestions on how to go about de-bugging would be greatly appreciated!
We got a similar problem, and it was solved by opening the needed port in EC2. thanks to https://kylegoslin.wordpress.com/2012/06/05/116/
I'm trying to use EQATEC Profiler to profile my ASP.Net app. I followed the instructions listed here. It worked the first time, but every since then, when I run my app, I don't get a "Profiled app started" message. Then when I click on the "Take snapshot" button, I get the following:
"Taking snapshot ...failed: The remote server returned an error: (404) Not Found."
Why can't it find my app?
If a profiled app encounters errors it will log these to the profiler.log file. By default you will find this in C:\Windows\Temp\EQATECProfilerLogs. Try to see if it holds some clues. You can also try to enable "Full logging" in the app options, which will at least output something to the log.
A profiled app is actually the "server" when talking to the profiler; it is the profiler that connects to the app, not the other way around. In your case it seems that the old app has stopped listening (otherwise the profiler's attempt to connect would simply be served by the old app), but the new app has not (could not?) started listening.
It seems strange, though, so my best suggestion is to examine the log-file. It will e.g. show if the app could not start its control-server and if so, why not.
1) Try rebuilding (in Equatec) your application. Make sure "enable runtime control" is enabled in the application options when you build.
1a) Try changing the port being used for runtime control.
2) Run your application through Equatec
3) Check if you have anything funny for firewall settings or similar. Some firewalls treat Equatec communication as traffic to be blocked.
4. If all else fails, just close your application normally. Even if taking snapshots fails, you can still see the profile once your application is closed.
Guess I should provide an update on this. The error was resolved once I downloaded the latest version.
