Create auth challengeMetadata does not show up in the signIn response

See original GitHub issue

Describe the bug When setting:

event.response.challengeMetadata = "00000000-0000-0000-0000-000000000000";
callback(null, event);

in the Cognito create auth lambda, the property does not show up in response from the call to Auth.signIn, which returns:


CognitoUser {
  username: 'xxxxxxx',
  pool: CognitoUserPool {
    userPoolId: 'eu-west-1_xxx',
    clientId: 'xxxxxxxxxxxxxxxxxxxxxxxxxxx',
    client: Client {
      endpoint: 'https://cognito-idp.eu-west-1.amazonaws.com/',
      fetchOptions: {}
    },
    advancedSecurityDataCollectionFlag: true,
    storage: InMemoryLocalStorage { store: {} }
  },
  Session: redacted',
  client: Client {
    endpoint: 'https://cognito-idp.eu-west-1.amazonaws.com/',
    fetchOptions: {}
  },
  signInUserSession: null,
  authenticationFlowType: 'CUSTOM_AUTH',
  storage: InMemoryLocalStorage { store: {} },
  keyPrefix: 'CognitoIdentityServiceProvider.xxxxxxxxxxxxxxxxxxxxxxxxxxx',
  userDataKey: 'CognitoIdentityServiceProvider.xxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
  challengeName: 'CUSTOM_CHALLENGE',
  challengeParam: {
    fingerprintId: '00000000-0000-0000-0000-000000000000',
    pinDigits: '[{"value":null,"label":"2nd"},{"value":null,"label":"4th"},{"value":null,"label":"5th"}]'
  }
}

As you can see I can probably work around it using the challenge parameters, but I was expecting to see challengeMetadata in the response.

The property is documented here,

@damien-monni nope. seems everyone, stalebot included, have their head in the sand on this one.

If you want to send metadata then you will need to send it in the publicChallengeParameters property - the only way you could possibly handle multiple challenges currently.

sorry aws but cognito is a dogs’s dinner.
