AWS Cognito adminCreateUser from java script SDK

Question

I'm trying to create a user in a AWS User Pool from an AWS Lambda

I tried with this script took from what seems to be the official JavascriptSDK for the AWS but can't get it working. http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/CognitoIdentityServiceProvider.html#adminCreateUser-property

I keep getting this error:ypeError: cognitoidentityserviceprovider.adminCreateUser is not a function

var cognitoidentityserviceprovider = new AWS.CognitoIdentityServiceProvider({apiVersion: '2016-04-18'});

var params = {
    UserPoolId: 'eu-west-1_XXXXXXXX', /* required */
    Username: '[email protected]', /* required */
    DesiredDeliveryMediums: [
        'EMAIL'
    ],
    ForceAliasCreation: false,
    MessageAction: 'SUPPRESS',
    TemporaryPassword: 'tempPassword1',
    UserAttributes: [
        {
            Name: 'email', /* required */
            Value: '[email protected]'
        },
        {
            Name: 'name', /* required */
            Value: 'Me'
        },
        {
            Name: 'last_name', /* required */
            Value: 'lastme'
        }
        /* more items */
    ]
};
cognitoidentityserviceprovider.adminCreateUser(params, function(err, data) {
    if (err) console.log(err, err.stack); // an error occurred
    else     console.log(data);           // successful response
    callback(null, data);
});

For adminCreateUser (you basically require the aws sdk, configure credentials, instantiate the client and call the specific operation).

var aws = require('aws-sdk');
aws.config.update({accessKeyId: 'akid', secretAccessKey: 'secret'});

var CognitoIdentityServiceProvider = aws.CognitoIdentityServiceProvider;
var client = new CognitoIdentityServiceProvider({ apiVersion: '2016-04-19 });
//your code goes here

Note that there might be different ways in which you can configure the AWS credentials to call the operation. You do need credentials as this is an authenticated operation. Other admin operations are similar, you just need to pass the appropriate parameters as JSON in the call.

According to this, the AWS SDK for JavaScript version 2.7.25 which contains the adminCreateUser operation should be available.
