I’m using firebase authentication using phone number. I have added my number for testing which works fine and even I can see captcha verifier for same. But if I try with another phone number I’m getting error below

[firebase_auth/invalid-app-credential] The phone verification request contains an invalid application verifier. The reCAPTCHA token response is either invalid or expired.

Code:

  Future<ConfirmationResult> authViaPhoneNo({
    required String phoneNo,
  }) async {
    return auth.signInWithPhoneNumber(phoneNo);
  }

  Future<User?> verifyOTP({
    required ConfirmationResult result,
    required String otp,
  }) async {
    final credential = await result.confirm(otp);
    return credential.user;
  }
}

Also If i use with captacha

 final captchaVerifier = RecaptchaVerifier(
     container: 'recaptcha',
     size: RecaptchaVerifierSize.compact,
     theme: RecaptchaVerifierTheme.dark,
     auth: FirebaseAuthPlatform.instance,
 );

I’m getting this error

DartError: Assertion failed: file:///Users/user-name/.pub-cache/hosted/pub.dev/firebase_auth_web-5.12.0/lib/src/firebase_auth_web_recaptcha_verifier_factory.dart:94:9
