React native 登录时未在apple身份验证中获取用户详细信息（React Native）？

我需要苹果登录时获取用户数据的帮助。我一直在尝试使用apple身份验证（React Native）登录。但是我没有得到任何用户的详细信息，所以我不能继续做剩下的事情。因此，有人能帮我解决我在代码中犯的错误吗。

导入的库：

导入{appleAuth，AppleButton， AppleAuthRequestOperation， AppleAuthRequestScope， AppleAuthCredentialState， AppleAuthError，}来自“@invertase/react native apple authentication”； 从“jwt解码”导入jwt_解码

export default class AppleLogin extends Component {
    constructor() {
        super();
        this.authCredentialListener = null;
        this.user = null;
        this.state = {
          credentialStateForUser: -1,
        }
      }
      componentDidMount() {
       
        this.authCredentialListener = appleAuth.onCredentialRevoked(async () => {
          console.log('Credential Revoked');
          this.fetchAndUpdateCredentialState().catch(error =>
            this.setState({ credentialStateForUser: `Error: ${error.code}` }),
          );
        });
    
        this.fetchAndUpdateCredentialState()
          .then(res => this.setState({ credentialStateForUser: res }))
          .catch(error => this.setState({ credentialStateForUser: `Error: ${error.code}` }))
      }
    
      componentWillUnmount() {
      
        this.authCredentialListener();
      }
    
      signIn = async () => {
        console.warn('Beginning Apple Authentication');

            ],
          });

            nonce,
            identityToken,
            realUserStatus /* etc */,
          } = jwt_decode(appleAuthRequestResponse.identityToken);
          alert("appleAuthRequestResponse2",email,user)
          this.user = newUser;
          alert("appleAuthRequestResponse 3",this.user )
          this.fetchAndUpdateCredentialState()
            .then(res => {alert('res',res),
            this.setState({ credentialStateForUser: res })})
            .catch(error =>
              this.setState({ credentialStateForUser: `Error: ${error.code}` }),
            );
    
    
          if (realUserStatus === appleAuth.UserStatus.LIKELY_REAL) {

          } else {
