Getting a FirebaseException ( [ Invalid authority field:[http: ] ) when trying to use FireBaseAuth on the Firebase Local Emulator

Question

I have an Android flutter app that I have connected to flutter and have setup the Firebase config successfully, and I have set it up to connect to a local Firebase emulators.

Emulators Enabled:

• Firestore: working fine. I can query documents
• Authentication: Getting an exception: [ Invalid authority field:[http: ]

Full error log:

I/flutter ( 8905): [firebase_auth/unknown] com.google.firebase.FirebaseException: An internal error has occurred. [ Invalid authority field:[http: ]

 firebase_core: ^1.4.0
 firebase_auth: ^3.0.0
 cloud_firestore: ^2.4.0
 google_sign_in: ^5.0.4

FirebaseAuth emulator at: 10.0.2.2:9099

My project's config in Firebase is also set up (Sha1 keys are set, etc). I'm trying to login using Google Sing In. What other config might I be missing that is causing the exception?

Answer 1

For Emulator: remove "http://" from firebaseAuth url, use only ip like "10.0.2.2" and port

Answer 2

检查您的 HTTP 链接并重新写入

Answer 3

In previous versions of Firebase Auth plugin, we used to write the port information in the url itself like

var url = 'http://localhost:9099';
// and then call useAuthEmulator like below
await FirebaseAuth.instance.useAuthEmulator(url);

but in later versions of Firebase Auth , the useAuthEmulator function was changed to accept the domain and port separately. Now its like below.

var url = 'localhost'; // Note you don't have to mention the protocol http or https
var port = 9099;
// and then call useAuthEmulator like below
await FirebaseAuth.instance.useAuthEmulator(url,port);

It seems like you were using an earlier version of Firebase Auth plugin, and then did a pub upgrade , thus, you changed to the second form shown above. But most probably, you might have forgotten to remove the protocol or port from the url .
