We are integrating phone auth in our application.We faced an error while integrating the error problem is [Error: [auth/missing-client-identifier] This request is missing a valid app identifier, meaning that Play Integrity checks, and reCAPTCHA checks were unsuccessful. Please try again, or check the logcat for more details.]

We had also enable Google Play Integrity API & followed the document also

Here's what we integrated into it
android/app/build.gradle
apply plugin: 'com.google.gms.google-services
implementation(platform("com.google.firebase:firebase-bom:33.2.0"))
implementation 'com.google.android.gms:play-services-safetynet:18.0.1'
implementation 'com.google.firebase:firebase-auth'

Code:-
const sendOtp = async () => {
try {
const confirmation = await auth().signInWithPhoneNumber(phoneNumber);
setVerificationId(confirmation.verificationId);
console.log('OTP sent');
} catch (error) {
console.error(error);
}
};
const confirmCode = async () => {
try {
const credential = auth.PhoneAuthProvider.credential(
verificationId,
code,
);
await auth().signInWithCredential(credential);
console.log('Phone authentication successful');
} catch (error) {
console.log(error);
}
};

We integrated into react native version 0.75.3

I completed all the basics check what is needed for these phone auth otp integration

same problem, any updates?

@IamMax279 there will not be updates on your project not having a valid app identifier, you have to make sure your app has a valid app identifier.

There's plenty of resources to help you debug this particular issue, for example see this stackoverflow thread for potential solutions.

One that I've seen a few times; replace your sha-1 and sha-256 keys (could be incorrect for a few reasons).

1. run ./gradlew signingReport in android/ directory of your app.
2. paste keys into the Firebase console for your app.
