Answer 1

Here is the solution.
Pre-requirement
If you want to use the credential in aws-sdk (Manual Process)
1. Create IAM User and Assign a Cognito role to your user.
2. Generate Access Key and Secret Key for that user.
3. Use that Access Key and Secret Key in aws-sdk.
Like This,
let AWS = require("aws-sdk");
AWS.config.update({
accessKeyId: "YOURKEY",
secretAccessKey: "YOURSECRET",
region: "YOURREGION"
});
Create object of CognitoIdentityServiceProvider class
const COGNITO_CLIENT = new AWS.CognitoIdentityServiceProvider({
apiVersion: "2016-04-19",
region: "us-east-1"
});
var poolData = {
UserPoolId: "XXXXXXXXX",
Username: "kurulezomi#themailpro.net",
DesiredDeliveryMediums: ["EMAIL"],
TemporaryPassword: "Abc#321",
UserAttributes: [
{
Name: "email",
Value: "kuri#themailpro.net"
},
{
Name: "email_verified",
Value: "true"
}
]
};
COGNITO_CLIENT.adminCreateUser(poolData, (error, data) => {
console.log(error);
console.log(data);
callback(null, {
statusCode: 200,
body: JSON.stringify(data)
});
});
Or else you can directly assign IAM Role to your EC2 Instance in that case you do not need to set credentials in AWS.config Section.

ABOUT THIS NODE.JS EXAMPLE: This example works with the AWS SDK for JavaScript version 2 (v2).
Purpose:
admin-create-user.js demonstrates how an administrator can use Amazon Cognito to create a user.
Inputs:
USERPOOLID
EMAIL
AWS configuration
const AWS = require("aws-sdk");
AWS.config.update({
accessKeyId : "Your accessKeyId ",
secretAccessKey: "secretAccessKey",
});
CREATE COGNITO_CLIENT
const COGNITO_CLIENT = new AWS.CognitoIdentityServiceProvider({
apiVersion: "2022-10-03",
region: "us-east-1",
});
CREATE USER
const createUser = async (user) => {
try {
const { emailId, password } = user;
const cognitoParams = {
UserPoolId: userPoolId,
Username: emailId,
UserAttributes: [
{
Name: "email",
Value: emailId,
},
{
Name: "email_verified",
Value: "true",
},
],
TemporaryPassword: password || "Password#123456789",
};
console.log(cognitoParams.TemporaryPassword);
let response = await COGNITO_CLIENT.adminCreateUser(
cognitoParams
).promise();
console.log(JSON.stringify(response));
return "user created";
} catch (err) {
throw Error(err);
}
};
