Nativescript-plugin-firebase: Cannot read property tasks of undefined

[tobydeh]

I've added the plugin to our project and followed the push-only instructions.

When running on device i get the following error:

System.err: TypeError: Cannot read property 'tasks' of undefined

Thanks for the report - what kind of device is this, and does it have Google Play Services installed?

[tobydeh]

One Plus 5T, Oxygen OS 5.1.5, Android version 8.1.0. Google play services is installed.

[tobydeh]

Upgrading to Oxygen OS 9.0.7, Android version 9 has fixed the issue.

[Nebulosar]

Also throws this error on my devices:

• Huawei P9 Lite, Android v 7.1
• Nexus 6P, Android v 7.0
• Nexus 5 Android 8.0

I am using nativescript + vue.
here my package:

  "dependencies": {
    "nativescript-plugin-firebase": "*",
    "nativescript-theme-core": "^1.0.6",
    "nativescript-ui-sidedrawer": "~7.0.0",
    "nativescript-vue": "~2.4.0",
    "rxjs": "~6.5.0",
    "tns-core-modules": "~6.0.0"
  },
  "devDependencies": {
    "@babel/core": "~7.1.0",
    "@babel/preset-env": "~7.1.0",
    "babel-loader": "~8.0.0",
    "nativescript-dev-webpack": "~1.0.0",
    "nativescript-vue-template-compiler": "~2.4.0",
    "node-sass": "^4.7.1",
    "vue-loader": "~15.4.0"
  },

Code:

var firebase = require("nativescript-plugin-firebase");

firebase.init({
    apiKey: "AIza...XXXXXX",    /
    databaseURL: "https://myApp-d41a2.firebaseio.com",
}).then(
    function () {
        console.log("firebase.init done");
    },
    function (error) {
        console.log("firebase.init error: " + error);
    }
);

Hope this helps with the issue

Same issue, Samsung A7. and LG G6.

[EddyVerbruggen]

@delanick is there a repo and reproduction path I can work with? Or ideas on a fix perhaps.

[Nebulosar]

It seems like in the storage.js file, var gmsTasks = com.google.android.gms.tasks; causes the trouble.
gms is undefined. I'm not hardcore android, so i do not really know what this is, or where to fix it.

Maybe this issue is somewhat related to and of any help? https://stackoverflow.com/questions/45692460/failed-to-resolve-com-google-android-gmsplay-services-in-intellij-idea-with-gr

Again, not my field of expertise..

[EddyVerbruggen]

Ah that one, yeah I took care of it here https://github.com/EddyVerbruggen/nativescript-plugin-firebase/commit/10a8d90d0013fe85bd3cb59292108d22842efef2 but the new version is not out yet. Will do soon!

[Nebulosar]

Nice @EddyVerbruggen ! Looking forward to the update!

[delanick]

Nice @EddyVerbruggen ! Looking forward to the update!

Ditto! :) Any idea of when @EddyVerbruggen ? :)

[EddyVerbruggen]

Working on it. When it's done.

[delanick]

@EddyVerbruggen Oh awesome! Was prepping myself spiritually to put the project on hold for a few weeks for when you have time :) You legend!

I also see you responded to my +1 on the issue on Friday - somehow I accidentally deleted the email notification and couldn't find it. Thought I was going crazy. Seems I don't need to send you a repo as you've identified the problem... Let me know if you still want me to share it :)

[EddyVerbruggen]

@delanick No worries, looks like this is tackled indeed.

I have a few other tasks to complete before the 9.1.0 version can be released. And there's a lot of testing involved, so can't rush it. I do aim to complete it early this week though.

[delanick]

@EddyVerbruggen Amazing! Thanks mate! Will keep an eye out for the update. Do you know if there is a way to subscribe to updates -> like having Github notify you when repos are updated?

[EddyVerbruggen]

@delanick You can get notified when releases are created here:

[delanick]

@EddyVerbruggen Ah awesome, thanks so much!

[delino12]

@EddyVerbruggen I'm also having this issue, currently using the latest nativescript version. Also experience TypeError: cannot read property 'tasks' of undefined. my android version is 8.1.0.

I will be very grateful to get your response on this.

[delino12]

@EddyVerbruggen I can also add you to the development repository if you want to get clearer view on the implementation.

[EddyVerbruggen]

@delino12 Which plugin version do you use?

[delino12]

"nativescript-plugin-firebase": "^9.1.0",

[delino12]

@EddyVerbruggen was wondering if missed out anything i followed all the steps and instructions carefully. I guess i will start debugging by the last 3 version.

[EddyVerbruggen]

If your issue is related to storage (like the OP) then 9.1.0 should have fixed it. Otherwise, please open a new issue and post your stacktrace (adb logcat will help).

[delino12]

@EddyVerbruggen Alright.

[delino12]

@EddyVerbruggen still haven't detect if it's related to storage yet.

[EddyVerbruggen]

@delino12 I see mlkit barcodescanning in your stacktrace. Did you enable that?

[delino12]

@EddyVerbruggen No I didn't. the only configuration was

{
  "external_messaging": true
}

[EddyVerbruggen]

@delino12 You mean literally this? It's important to be precise. I really need a repo to look at.

[delanick]

@EddyVerbruggen I also updated to the latest plugin version and am still facing this exact issue. My repo is empty, it's a blank app with only the plugin installed and required google-services file added to the project, but happy to share with you :)

[EddyVerbruggen]

@delanick are you sure you don't require/import the plugin anywhere?

[delanick]

@EddyVerbruggen apologies, I wasn't quite clear enough. Yes, I do require and init the plugin in my app.js file. My assumption is that that's where it's breaking.

[EddyVerbruggen]

@delanick OK, then the demo-push app in this repo should crash as well. Let me try that once I'm done with a bunch of other stuff 😅

[delanick]

@EddyVerbruggen Ok cool, don't work too hard now ya hear? :P

[EddyVerbruggen]

@delanick I just bumped demo-push to NativeScript 6 and it worked without problems on my emulator (which has Play services installed).

So can you either share that problematic repo with me, or try the demo-push app yourself? For the latter:

git clone https://github.com/EddyVerbruggen/nativescript-plugin-firebase
cd nativescript-plugin-firebase/src
npm i
npm run demo-push.android

[delanick]

@EddyVerbruggen will do both. Sending my project to your gmail account.

[delino12]

@EddyVerbruggen i will clone the source repo and run a demo on android. @delanick I guess yours should be working now. You should get a notification by now i've sent you an invite.

[delanick]

@delino12 I didn't have a chance to get the build done, will do it tonight. What invite?

[delanick]

@EddyVerbruggen cloned the project and tried building via Sidekick. On opening it in Sidekick it flags the project as not being compatible with {N} 6.

Running it through CLI failed even with following all those steps. Wouldn't allow me to build via CLI, not sure why.

[EddyVerbruggen]

@delino12, invite failed I guess:

[EddyVerbruggen]

@delanick In the project you emailed me, this filename is incorrect, that will screw things up for sure:

[delino12]

@EddyVerbruggen my apologies for that, Just sent you another here on github. https://github.com/delino12/zlay-nativescript/invitations thanks.

[delanick]

@EddyVerbruggen Holy hell, yep that'll do it! That's a combination of late night work and multiple projects. Will fix it on that machine and try again.

So I have the project on a different machine with the correct filename, and am now getting the build failed due to the firebase-copy-google-services.json hook not working. Below:

Build failed. Failed to execute hook: D:\NS Projects\PropMan\hooks\after-prepare\firebase-copy-google-services.js
