AWS Cognito User Pool AdminCreateUser in lambda returns no error nor data

I created an AWS Lambda function to test new Cognito User Pool account creation but no account was created in user pool and no error shown in console log. I checked AWS Cloud Watch but no error was reported in cloud watch also.

START RequestId: ..... Version: $LATEST
END RequestId: .....
REPORT RequestId: .....  Duration: 80.12 ms  Billed Duration: 100 ms Memory Size: 128 MB Max Memory Used: 84 MB

I changed my Lambda function to something simpler; describeUserPool. Still no error was thrown and no user pool info was printed in console. I added a console.log print within the describeUserPool callback function but that did not print.

The lambda function was created using AWS Console Lambda inline editor. Lambda function has AmazonESCognitoAccess policy attached (this policy has List/Read/Write access level to Cognito User Pools).

Can anyone shed some lights on what I've gotten wrong? Thank you very much in advance.

var aws = require('aws-sdk');
aws.config.update({
    accessKeyId: 'access_key_id', 
    secretAccessKey: 'secret_access_key',
    region: 'us-east-1',
    apiVersion: '2016-04-18'
});
var cognito = new aws.CognitoIdentityServiceProvider();
var params = {
    UserPoolId: 'us-region-user-pool-id'
};

exports.handler = async (event) => {
    cognito.describeUserPool(params, function(err, data) {
        console.log('hello from inside function');
        if (err) {
            console.log(err);
        } else {
            console.log(data);
        }
     });
};

If I included an incorrect params in AdminCreateUser it reported error

var aws = require('aws-sdk');
    aws.config.update({
        accessKeyId: 'access_key_id', 
        secretAccessKey: 'secret_access_key',
        region: 'us-east-1',
        apiVersion: '2016-04-18'
    });


var cognito = new aws.CognitoIdentityServiceProvider();
var params = {
    UserPoolId: 'us-region-user-pool-id'
    Username: 'someone',
    TemporaryPassword: '11223344',
    DesiredDeliveryMediums: 'EMAIL',
    MessageAction: 'SUPPRESS',
    UserAttributes: [
    {
      Name: 'Email',
      Value: '[email protected]'
    },
    {
        Name: 'Family_Name',
        Value: 'One'
    },
    {
        Name: 'Given_Name',
        Value: 'Some'
    },
    {
        Name: 'Phone_Number_verified',
        Value: 'True'
    },
        {
        Name: 'Email_verified',
        Value: 'True'
    }

  ],
};

exports.handler = async (event) => {

    cognito.adminCreateUser(params, function(err, data) {
        console.log('hello from inside function');
        if (err) {
            console.log(err);
        } else {
            console.log(data);
        }
     });
};

I received the following error message in Lambda inline editor console:

Hi, can you see if it was invoked. Check CloudWatch metric – Chris Williams
Triggered "Test" in Lambda console and Cloud Watch confirmed that it ran successfully. Timestamp Message There are older events to load. Load more. 2020-05-31T16:59:07.766-04:00 START RequestId: 1ea1741e-d9e7-4991-af9d-f72bf73b1133 Version: $LATEST 2020-05-31T16:59:08.202-04:00 END RequestId: 1ea1741e-d9e7-4991-af9d-f72bf73b1133 2020-05-31T16:59:08.202-04:00 REPORT RequestId: 1ea1741e-d9e7-4991-af9d-f72bf73b1133 Duration: 434.49 ms Billed Duration: 500 ms Memory Size: 128 MB Max Memory Used: 83 MB Init Duration: 337.21 ms. However there's no CloudWatch metric for Cognito. – billyap
I changed the function call back to AdminCreateUser. That did not produce any CloudWatch log. Looks like lambda is not triggering CognitoIdentifyServiceProvider function call at all. – billyap

Found this post cognito admin not giving error. Suggestion by @thopaw solved the issue that I was having.

By changing it to promise() base it works as expected. Thank you guys for your time.

In case anyone came across this, below is the updated code.

exports.handler = async (event, context) => {
    console.log('starts');
    var data;
    try {
        const data = await cognito.adminCreateUser(params).promise();
    } catch (error) {
        console.log(error);
    }
};
