Flutter Firebase手机号认证非测试号码报错17499（错误码39）求助

我在使用Flutter和Dart为应用集成Firebase手机号认证功能时，遇到以下问题：输入非测试号码时，Recaptcha界面弹出后会出现错误：

[SmsRetrieverHelper] SMS verification code request failed: unknown status code: 17499 Error code:39

使用测试号码时一切正常。

AuthController代码 #

class AuthController extends GetxController{
  final _auth = FirebaseAuth.instance;
  var verificationId = ''.obs;
  TextEditingController phoneController = TextEditingController();
  var otp = '';
  var _resendToken;

  Future<void> phoneAuthentication(String phone) async{

    await _auth.verifyPhoneNumber(
      phoneNumber: phone,

      verificationCompleted: (credential) {},
      codeSent: (verificationId, resendToken){
        this.verificationId.value = verificationId;
        this._resendToken = resendToken;
        debugPrint('code is sent');
        Get.toNamed(Verification.routeName);
      },
      timeout: const Duration(seconds: 120),
      codeAutoRetrievalTimeout: (verificationId){
        this.verificationId.value = verificationId;
      },
      verificationFailed: (FirebaseAuthException e){
        debugPrint('error message: ${e.message}');
        debugPrint('error code: ${e.code}');
        debugPrint('error stackTrace: ${e.stackTrace}');
        showCustomToast(msg: 'sending failed error code: ${e.code}');
      },
      forceResendingToken: this._resendToken,
    );
  }

  Future<void> verifyOTP(String otp) async{

    try {
      PhoneAuthCredential credential = PhoneAuthProvider.credential(
          verificationId: verificationId.value, smsCode: otp);
      UserCredential user = await _auth.signInWithCredential(credential);
      debugPrint('${credential.smsCode}: credential.smsCode');

      if (user.user != null) {
        Get.offAndToNamed(Home.routeName);
      }
    }
    catch (e){
      showCustomToast(msg: 'wrong code');
    }
  }

}

已完成的配置 #

• 将应用的SHA-1和SHA-256与Firebase关联
• 在Firebase控制台启用手机号认证
• 在Google Cloud启用Google Play Integrity API
• 完成App Check注册并下载最新的google-services.json
• 尝试升级所有依赖至最新版本

以上操作后问题仍未解决，寻求帮助。
