Auth

Which platforms are affected?

Android, iOS

Description

Using the verifyPhoneNumber to send an SMS code to a dedicated phone number fails with the following error: "An internal error has occurred, print and inspect the error details for more information."

This happened using versions 4.6.3 as well as version 5.2.0.

Reproducing the issue

1. Create a flutter project and add firebase_auth, firebase_core packages (5.2.0 and 3.4.0 respectively)
2. Try to trigger await firebase.FirebaseAuth.instance.verifyPhoneNumber with a valid phone number format

Expected behavior: verificationCompleted gets triggered after a successful verification as expected

Actual behavior: receiving 500 internal error with the message: [firebase_auth/internal-error] An internal error has occurred, print and inspect the error details for more information.

Firebase Core version

2.14.0 and 3.4.0

Flutter Version

3.16.9

Relevant Log Output

code = "internal-error"
message = "An internal error has occurred, print and inspect the error details for more information."

I'm having the same issue even with firebase_core 3.0.0 and firebase_auth 5.0.0

Hi, thanks for the report. Are you using a test number?

[dhurem]

No, I was testing with valid phone numbers from multiple countries.

Note: I made sure I have not set up any region restrictions on firebase itself.

I'm trying to find out the causes but there are no other error message. Last month when i use 4.9 version, there was no problem. but, why it makes error. I'm not sure even when this error started. I had version up but it still in there. firebase_auth: ^5.2.0, firebase_core: ^3.4.0

I have tested on Firebase Auth iOS but i received "invalid-app-credential" which I think is because of update to firebase-ios-sdk. Apparently it has been fixed in latest version (11.2.0) so I will raise a PR for bumping iOS version: https://github.com/firebase/firebase-ios-sdk/issues/13479

I logged in with android phone auth successfully.

@russellwheatley Looks like we got the same error.

I got an error different from the original post when calling verifyPhoneNumber() on a real iOS device with a real phone number. It received an [firebase_auth/invalid-app-credential] error from verificationFailed callback:

error:

flutter: [firebase_auth/invalid-app-credential] Token mismatch

plugins version:

firebase_core: ^3.3.0
firebase_auth: ^5.0.0

Same issue here.

I suspect the problem lies in the communication between FMC and Apple’s remote background notification system within the package.

In my case, the iOS emulator works fine, and disabling push notifications allows me to trigger reCAPTCHA and send SMS verification codes on a real device.

Workaround:

  firebase_auth: 5.1.4
  firebase_core: 3.3.0

Still not fixed
