[Firebase_auth] "QUOTA_EXCEEDED : Exceeded quota for sending verification codes" Using phone number for testing on iOS emulator

[yamauchieduardo]

I'm using Firebase Auth for 3 years and now a strange behavior started to appears. When I use some registered phone number for test (Phone and sms code Registered in the whitelist), after sometime I'm not able to use a phone number with sms to authenticate in my tests, because the backend returns "QUOTA_EXCEEDED : Exceeded quota for sending verification codes."

But I'm just use Phone number registered for test.

This behavior is strange because I'm don't notice that on Android Emulator, just in iOS Emulator.

Notice in firebase_auth: ^3.3.6version

Thanks for the attention.

@yamauchieduardo
Does it only occur when using iOS simulator ? Can you try it on a physical device to see if you still get same error ?
Since you testing on iOS simulator, the SMS code must be getting verified somehow, something like auto-verify. It would be good to verify this on a physical device to confirm.

[yamauchieduardo]

@darshankawar I used a real device and sadly happen too.
A plus information: before start the authentication I setup "appVerificationDisabledForTesting" and forceRecaptchaFlow.

  await FirebaseAuth.instance.setSettings(
        appVerificationDisabledForTesting: true,
        forceRecaptchaFlow: false,
      );

This behavior is really strange, I just start to notice in the latest versions. Some months ago this issue didn't occurs.
