React-Redux 应用程序中的 AWS Cognito 'Index.handler' 错误

Question

我正在尝试学习如何将 AWS Cognito Auth 集成到自定义 React-Redux 应用程序中。我在注册活动期间遇到了一个问题，来自 cognito 的以下错误消息：

"message:"CustomMessage 失败，错误 index.handler 未定义或未导出。"}"

此错误是由我的“注册”操作生成的。所以我知道 react 正在准确地将表单数据传递给 redux。 Cognito 控制台也成功显示了一个注册用户，但是没有发送用户在注册过程后应该收到的电子邮件确认（我正在使用真实的电子邮件进行测试）。

以下是我在注册过程中的操作和缩减程序。任何建议都会有所帮助。

--仅供参考，我确保我的 Amplify 配置位于根目录中，并且我的 src 目录有一个 index.js 文件。我也使用电子邮件作为用户名。

动作

// SIGN UP USER
export const signup = ({
  firstname,
  lastname,
  username,
  password,
  phonenumber,
}) => async (dispatch) => {
  try {
    const res = await Auth.signUp({
      username,
      password,
      attributes: {
        given_name: firstname,
        family_name: lastname,
        phone_number: phonenumber,
      },
    });

    console.log(res);
    dispatch({
      type: SIGNUP_SUCCESS,
      payload: res,
    });
    // get if user is signed in
    dispatch(loadUser());
  } catch (error) {
    console.log(error);

    dispatch({
      type: SIGNUP_FAIL,
    });
  }
};

减速器

  case SIGNUP_SUCCESS:
      return {
        ...state,
        ...payload,
        isAuthenticate: true,
      };
    case AUTH_ERROR:
    case LOGOUT:
      return {
        ...state,
        isAuthenticated: false,
        user: null,
      };

反应形式

const SignUp = ({ signup, isAuthenticated }) => {
  // collect data from form
  const [formData, setFormData] = useState({
    firstname: '',
    lastname: '',
    username: '',
    password: '',
    phonenumber: '',
  });
  //extract data into formData object
  const { firstname, lastname, username, password, phonenumber } = formData;
  // collect input data on click
  const onChange = (event) =>
    setFormData({ ...formData, [event.target.name]: event.target.value });

  // call action on submit of form
  const onSubmit = async (event) => {
    event.preventDefault();
    try {
      // call signup action
      signup({ firstname, lastname, username, password, phonenumber });
      //this.props.history.push('/welcome');
      return <Redirect to='/welcome' />;
    } catch (error) {
      console.log(error.message);
    }
  };

  // if user is already signed up/in then return to dashboard
  if (isAuthenticated) {
    return <Redirect to='/dashboard' />;
  }

  return (

const mapStateToProps = (state) => ({

export default connect(mapStateToProps, { signup })(SignUp);

该错误消息听起来像是 Lambda 函数失败。您是否偶然将 Cognito 设置为使用自定义注册消息触发 Lambda 函数？

听起来您使用自己的 Lambda 函数自定义了“发送电子邮件确认”行为，但该函数未正确编写/打包/部署。
