amplify-js: user.completeNewPasswordChallenge is not a function

You can simply use the predefined amplify method like below. const currentUser = await Auth.currentAuthenticatedUser();

@goatandsheep When you get resolved from Auth.signIn() with that user object, you are not actually signed in because you need to complete the new password. So at that moment Auth.currentSession and Auth.currentAuthenticatedUser won’t work because you are not signed in. You need to directly use that user object returned from Auth.signIn() to help you finish the login process.

Thank you. Your response helped in identifying my mistake. The user object passed to Auth.completeNewPassword was different from the one returned by signin method so it was failing. After changing to use the object returned by signin it works correctly. Confirmed in cognito console that the status of user does change correctly.

@goatandsheep hi can you confirm that the userFromLoginAttempt object should be a CognitoUser object?

I think it should be a method to create a CognitoUser instance from the returned object after stringify it and parse it again!

Anyone can confirm that the user object returned from signIn can be stored in the session storage via JSON.parse()? When the user sign in at the first time, I redirect the page to the change password one, however when I use the stored user object to call the completeNewPassword() it always says the error as user.completeNewPasswordChallenge is not a function

Here is some manual parsing to create CognitoUser instance from the parsed object (cognitoObject):

const pool = new CognitoUserPool({
      UserPoolId: cognitoObject.pool.userPoolId,
      ClientId: cognitoObject.pool.clientId,
      endpoint: cognitoObject.client.endpoint,
      Storage: window.localStorage,
      AdvancedSecurityDataCollectionFlag: cognitoObject.advancedSecurityDataCollectionFlag,
})
const cognitoUser = new CognitoUser({
      Username: cognitoObject.username,
      Pool: pool,
      Storage: window.localStorage,
})

cognitoUser.Session = cognitoObject.Session

await Auth.completeNewPassword(cognitoUser, newPassword, cognitoObject.challengeParams)

@mikeRChambers610 you have to pass the object returned by Auth.signIn() instead of a username string. There isn’t anything in the session yet, so @nikhilknoldus suggestion will not work

Here’s an example using React: https://gist.github.com/davekiss/9af08fde4ce2d40e306a35028583d6e5

I tried this (long story above - sessionstorage stores the same format as localstorage) and the object wasn’t recognized properly. It needs to be a CognitoUser object. You’re going to have to figure out how to pass it directly or put it in a 3rd party store like Redux or even Amplify Cache

you’re missing a lot in your workflow. Here let me help you out:

aws_amplify__WEBPACK_IMPORTED_MODULE_0__["Auth"].signIn(userNameField.value, passwordField.value)
  .then(user => {
    console.log(user);
    MessagesDiv.innerHTML = "Sign in success";
    if (user.challengeName === "SMS_MFA" || user.challengeName === "SOFTWARE_TOKEN_MFA") {
      aws_amplify__WEBPACK_IMPORTED_MODULE_0__["Auth"].confirmSignUp(/* TODO */)
    } else if(user.challengeName === "NEW_PASSWORD_REQUIRED"){
      aws_amplify__WEBPACK_IMPORTED_MODULE_0__["Auth"].completeNewPassword( VerifyUser.value, 'NewPassword2018')
        .then(() => {
          MessagesDiv.innerHTML = "Sign in success. Password updated";
          console.log('Password updated');
        })
        .catch(e => {
            MessagesDiv.innerHTML = "failed with error" + e;
            console.log('failed with error', e);
        });
    } else if (typeof user.challengeName !== 'undefined') {
      console.error(user.challengeName)
    }
    function checkUser(user) {
      aws_amplify__WEBPACK_IMPORTED_MODULE_0__["Auth"].verifiedContact(user)
        .then((data) => {
          console.log("verification result", data);
          if (Object.keys(data.verified).length > 0) {
            console.log("Successful login")
          } else {
            aws_amplify__WEBPACK_IMPORTED_MODULE_0__["Auth"].verifyContact(/* TODO */)
          }
        }
    }
    checkUser(user)
