i am getthing SMS verification code request failed: unknown status code: 17499 Internal error encountered. error on my Flutter app while sending OTP.
this code was working perfectly 2 days ago, but yesterday when tried this, it didn't work. i thought I messed configuration so I created a new flutter project and did it's firebase configuration from the beginning but getting same error.

My Code is :

sendOTP() async {
String phoneNumber = countryCodeController.text + phone;

try {
  await FirebaseAuth.instance.verifyPhoneNumber(
    phoneNumber: phoneNumber,
    verificationCompleted: (PhoneAuthCredential credential) async {
      await firebaseAuth.signInWithCredential(credential);
    },
    timeout: Duration(seconds: 60),
    verificationFailed: (FirebaseAuthException e) {
      print('Failed to verify phone number: ${e.message}');
    },
    codeSent: (String verificationId, int? resendToken) async {
      print('OTP sent: $verificationId');
      SignInPage.verify = verificationId;
      Get.off(OTPPage());
    },
    codeAutoRetrievalTimeout: (String verificationId) {
      print('OTP auto retrieval timeout: $verificationId');
    },
  );
} catch (e) {
  print('Error sending OTP: $e');
}

}

Yes, by downgrading package version it started working perfectly.
