Try to load the config using the AWS.Config class.

Example:

require('dotenv').config();
const AWS = require('aws-sdk');



const SESConfig = {
    apiVersion: "2010-12-01",
    accessKeyId: process.env.AWS_SECRET_KEY,
    accessSecretKey: process.env.AWS_SECRET_KEY,
    region: process.env.AWS_SES_REGION
}

let config = new AWS.Config(SESConfig); // Load the configuration like this. 
/*
Or you could update the config like this.
AWS.config.update(SESConfig);
*/


var params = {
    Source: 'xyz045@gmail.com',
    Destination: {
        ToAddresses: [
            'yyy45@gmail.com'
        ]
    },
    ReplyToAddresses: [
        'xyz05@gmail.com',
    ],
    Message: {
        Body: {
            Html: {
                Charset: "UTF-8",
                Data: 'IT IS <strong>WORKING</strong>!'
            }
        },
        Subject: {
            Charset: 'UTF-8',
            Data: 'Node + SES Example'
        }
    }
};
new AWS.SES().sendEmail(params).promise().then((res) => {
    console.log(res);
}).catch(error => {
    console.log(error)
});
