Create user with custom attribute using AdminCreateUser in AWS Cognito

Question

I am trying to create user in AWS Cognito with adminCreateUser API with the below code

var cognitoidentityserviceprovider = new AWS.CognitoIdentityServiceProvider();

var params = {
      UserPoolId: "us-east-1_302HlhnaC", /* required */
      Username : "[email protected]",
      ForceAliasCreation: true,
      TemporaryPassword: '[email protected]',
      UserAttributes: [
        {
          Name: 'given_name', /* required */
          Value: 'test'
        },
        {
          Name: 'family_name', /* required */
          Value: 'kumar'
        },
        {
          Name: 'name', /* required */
          Value: 'test'
        },
        {
          Name: 'custom:dob', /* required */
          Value: '1990-07-25'
        },
        {
          Name: 'email', /* required */
          Value: '[email protected]',
        },
        {
          Name: 'email_verified', /* required */
          Value: 'true',
        }
        /* more items */
      ],

};


cognitoidentityserviceprovider.adminCreateUser(params, function(error, data) {
    console.log(error,data);
    res.send("test");
});

It always throwing following exception : InvalidParameterException: Attributes did not conform to the schema: custom:dob: Attribute does not exist in the schema.

Is am doing anything wrong,if yes please let me know the solution.

Thanks

You must add the custom attribute ahead of time. You can create custom attributes by visiting the User Pool and clicking the Attributes link.
