I'm trying to get the Firebase authentication/sync running in the "Topeka" Polymer-sample.
This is what I've done:
Checked out topeka-master from GitHub
Ran bower install
Created a new Firebase-account and added the FirebaseIO-URL of the newly created project to topeka-datasource.html and topeka-leaderboard.html
Enabled anonymous auth in the Firebase project
Everything works fine if I use the .../?test-flag (which doesn't use Firebase)
Without the flag, I'm getting the following exceptions in Firefox (33.0.3):
Exception caught during observer callback: .locationChanged#data:text/javascript;charset=utf-8,%0A%20%20%0A%20%20Polymer('firebase-login'%2C%20%7B%0A%0A%20%20%20%20%2F**%0A%20%20%20%20%20*%20Fired%20when%20user%20is%20logged%20in%0A%20%20%20%20%20*%20%0A%20%20%20%20%20*%20%40event%20login%0A%20%20%20%20%20*%2F%0A%0A%20%20%20%20%2F**%0A%20%20%20%20%20*%20Fired%20when%20user%20is%20logged%20out%0A%20%20%20%20%20*%20%0A%20%20%20%20%20*%20%40event%20logout%0A%20%20%20%20%20*%2F%0A%0A%20%20%20%20%2F**%0A%20%20%20%20%20*%20Fired%20when%20an%20error%20occurred%20logging%20in%0A%20%20%20%20%20*%20%0A%20%20%20%20%20*%20%40event%20error%0A%20%20%20%20%20*%2F%0A%0A%20%20%20%20%2F**%0A%20%20%20%20%20*%20Fired%20when%20user%20is%20created%20(password%20provider%20type)%0A%20%20%20%20%20*%20%0A%20%20%20%20%20*%20%40event%20user-created%0A%20%20%20%20%20*%2F%0A%0A%20%20%20%20%2F**%0A%20%20%20%20%20*%20Fired%20when%20user%20changes%20their%20password%20(password%20provider%20type)%0A%20%20%20%20%20*%2"[…] observe.js:753

I'm trying to use Google Cloud Text-to-Speech API in Meteor app, but get an error on the Meteor console and crash when trying to use the import function described in the instructions:
("Uncaught TypeError: Cannot convert undefined or null to object at Function.getPrototypeOf (<anonymous>)")
Here's what I've done (in app directory) before starting meteor:
meteor npm install google-tts-api
export GOOGLE_APPLICATION_CREDENTIALS="/data/authenticationinfo.json"
The problems are related to the inclusion of this line at the top of my js file:
import textToSpeech from '#google-cloud/text-to-speech';
This line cause the following Meteor startup error on the console:
"Unable to resolve some modules: "http2" in /app/node_modules/#grpc/grpc-js/build/src/channel.js (web.browser)
If you notice problems related to these missing modules, consider running:
meteor npm install --save meteor-node-stubs
Actually, I ran the above command, but it has no effect. When I run start the app, it crashes quickly with the error :
Uncaught TypeError: Cannot convert undefined or null to object

I have tested it on a barebones node app, and my Google authentication json file works fine, so that's definitely not the problem.
I realize there are are some Meteor packages for Google TTS, but they're really old and use Google Translate (which won't work for long) instead of the new cloud services.
So, it turns out the import has to happen on the server side, NOT the client side.
Goal
Use the firebase emulator and deploy firebase cloud functions locally for test and debug.
Issue
When firebase serve is run, it fails with - Error: Certificate object must be an object.
What's been tried
Following Google's documentation here, the instructions include
these steps:
To set up admin credentials for emulated functions (other than Cloud
Firestore and Realtime Database):
Open the Service Accounts pane of the Google Cloud Console.
Make sure that App Engine default service account is selected, and use the options menu at right to select Create key.
When prompted, select JSON
for the key type, and click Create. Set your Google default
credentials to point to the downloaded key:
$ export GOOGLE_APPLICATION_CREDENTIALS="path/to/key.json"
$ firebase functions:shell
OR
$ firebase serve --only functions
Completing these instructions and running firebase serve... fails. Here are the logs:

Question
How do I fix these two errors?
I have firebase-functions installed, and have tried npm i --save firebase-functions
⚠ functions: Failed to load functions source code. Ensure that you have the latest SDK by running npm i --save firebase-functions inside the functions directory.
Thinking this has to do with GOOGLE_APPLICATION_CREDENTIALS, but I'm not sure how to verify or check what's happening here.
⚠ functions: Error from emulator. Error occurred while parsing your function triggers.
Error: Certificate object must be an object.
UPDATE
Further along in the documentation, it reads:
If you're using custom functions configuration variables, run the
following command in the functions directory of your project before
running firebase serve.
firebase functions:config:get > .runtimeconfig.json
After running this command, I no longer get the certificate error. Woot! However, I am getting new failures and not many hints from the logs.

});
Answer
Further along in the documentation, it reads:
If you're using custom functions configuration variables, run the
following command in the functions directory of your project before
running firebase serve.
firebase functions:config:get > .runtimeconfig.json
This project is using custom functions configuration variables. So, after running the config command, I no longer get the certificate error. Woot!
I am trying to login Facebook with Firebase. I have installed all the libraries required and completed the required configuration. Still, whenever I try to start my app it is giving me this error:

Able to solve this with below changes :
Just go to the below file in Ionic
plugins/cordova-universal-links-plugin/hooks/lib/android/manifestWriter.js
I fixed issue by changing pathToManifest as below:
var pathToManifest = path.join(cordovaContext.opts.projectRoot, 'platforms', 'android', 'cordovaLib', 'AndroidManifest.xml');
to
var pathToManifest = path.join(
cordovaContext.opts.projectRoot,
'platforms',
'android',
'app',
'src',
'main',
'AndroidManifest.xml');
For anyone that's looking into this these days, the actual fix for this was published by someone which you can pull in as a cordova plugin https://github.com/nordnet/cordova-universal-links-plugin/issues/133#issuecomment-369260863
#okaufmann you can use the changed version of the plugin. since it's not merged in the nordnet repository, you must remove the plugin and install again using:
cordova plugin add https://github.com/walteram/cordova-universal-links-plugin
After doing...
cordova plugin rm cordova-universal-links-plugin
cordova plugin add https://github.com/walteram/cordova-universal-links-plugin
.. my project was able to build successfully.
You need to update the AndroidManifest path in the plugin, which seems to be outdated. Check out this:

So I've done the todo and leaderboard tutorials and now am excited to begin routing - seems like iron router is the way to go so I install it to my project using
mrt add iron-router
Seems to install ok so I start meteor and navigate to localhost:3000 and my console lights up with:
Uncaught TypeError: undefined is not a function
helpers.js:141 Uncaught TypeError: Cannot read property 'prototype' of undefined
router.js:61 Uncaught TypeError: undefined is not a function
global-imports.js?784bc180a149e4c10dff977a7f114df67d9952c6:3 Uncaught TypeError: Cannot read property 'RouteController' of undefined
template.tutorialexample.js?e119ff8df948cfe8167f49eb28794995a594841c:2 Uncaught ReferenceError: Template is not defined
tutorialexample.js?a4ef596255404350be2cc45303caea02f934cd17:1 Uncaught ReferenceError: Meteor is not defined
Mind you this is a default app, haven't touched a thing.
So if someone could point me in the right direction that would be great. I did read somewhere that I should be using 0.8.2 version of iron router - and I then did change my smart.json file to contain:
{
"packages": {
"iron-router": "0.8.2"
}
}
and then did meteor update etc but still no luck. So any help anyone could provide would be great.
Meteor has changed quite a bit & the instructions/tutorial you've been following is a bit dated.
Previously mrt was part of the meteorite packaging system, from Meteor 0.9.0 it has been integrated directly into meteor.
So now you do:
meteor add iron:router
To add it to your project. Once you start your app up it should present a basic template on how to use it.
I'm getting the following error - Uncaught ReferenceError: Tracker is not defined
I am running meteor under windows(meteor version 0.8.3).
The code is in my templates js file.
Tracker.autorun(function (c) {
if (MovieTrailers.find().fetch().length == 0)
return;
c.stop();
PlayCurrentTrailer();
});
So far I have tried :
meteor add deps
But that didn't work.
Is tracker available under 0.8.3? or am I missing a package?
tracker is the new name of deps, so replace the occurrence of tracker in your code with deps and you're good to go.
Try to avoid running older versions of Meteor to develop new code, can't you run a VM or use an online service like Nitrous.io for development purpose, as deploying a Meteor app to production in a Windows environment for the moment is not going to happen anytime soon ?
