Flutter app giving UNAUTHENTICATED errors when calling Firebase cloud functions directly

Question

I tried using firebase cloud functions oncall method directly from my FLUTTER app and it keeps giving me an UNAUTHENTICATED error even when I am logged in Flutter app code

CloudFunctions function = CloudFunctions.instance;
final HttpsCallable createCallable = function.getHttpsCallable(functionName: 'two_create')
  ..timeout = const Duration(seconds: 30);

try {
  final HttpsCallableResult result = await createCallable.call({
    'stay': 'con50',
    'open': false
  });

  print(result.data);
}on CloudFunctionsException catch(e){
  print('-----------------------------------------------');
  print(e.code); print(e.message); print(e.details);
  print('-----------------------------------------------');
}

dynamic user = await FirebaseAuth.instance.currentUser();
print(user.uid);

I got this error

I/flutter (19466): -----------------------------------------------
I/flutter (19466): UNAUTHENTICATED
I/flutter (19466): UNAUTHENTICATED
I/flutter (19466): null
I/flutter (19466): -----------------------------------------------
I/flutter (19466): eMTX6OcYPOSeYdimmCSqjbnnmWM2

I tried printing out the uid to show I am currently signed in and I am currently using an android device for testing.

This is the function I am calling from my app

exports.two_create = functions.https.onCall(async (context,data)=>{
    var oncall = require('./httponcall');

    var text = await oncall.create(admin,allRef.one2,context,data);
    return text;
})

And I didn't get any logs from Firebase console when it was triggered

Solution

1. first update the firebase tools and dependencies to latest.

https://firebase.google.com/docs/functions/get-started?authuser=0#set-up-node.js-and-the-firebase-cli

npm install firebase-functions@latest firebase-admin@latest --save

npm install -g firebase-tools

2. after deploy

3. go to Google cloud console(GCP) not the firebase console GCP sidebar > Cloud functions > select your function go to PERMISSIONS >ADD > "allUsers"> Firebase > Firebase Viewer

do this at your own risk iam not any cloud devloper . i dont know the risk of adding allUsers like this iam new to flutter devlopment

Please edit the question to show the function code that you're trying to invoke, and any logs that it might be generating.

If the function isn't actually being invoked (you find no logs), then contact Firebase support for assistance. support.google.com/firebase/contact/support

This might be a matter of Node version. Please take a look: stackoverflow.com/questions/56120115/…

I have the same issue!

I tried changing the node version I still got the same error

[Hannah Stark]

For me the issue was that the invoker was not set on console.cloud.google.com/functions/details

I think @HannahStark is referring to this cloud.google.com/functions/docs/securing/…, have you checked that?
