After poking around, the AWS SDK for JavaScript seems to have two versions:

• Version 2 under @aws-sdk: https://www.npmjs.com/package/aws-sdk
• Version 3 under @aws-sdk/client-*: e.g., https://www.npmjs.com/package/@aws-sdk/client-ses

Version 2 of the SDK is meant to be entering maintenance mode in 2023.

Now that this first layer of confusion is cleared out, the AWS SES API also has 2 versions:

• SES API v1: https://docs.aws.amazon.com/cli/latest/reference/ses/index.html
• SES API v2: https://awscli.amazonaws.com/v2/documentation/api/latest/reference/ses/index.html

So based on this investigation, I presume that the packages points to the different API versions.

The key and the secret need to be in the credentials object of the configuration object.

Also, for CloneReceiptRuleSetCommand, you need to provide OriginalRuleSetName and RuleSetName.

So, it should be like this:

import {
  SESClient,
  CloneReceiptRuleSetCommand,
} from "@aws-sdk/client-ses";

const client = new SESClient({
  credentials: {
    accessKeyId: "MYKEY",
    secretAccessKey: "MYOTHERKEY"
  },
  region: "us-east-1",
});

const params = {
  OriginalRuleSetName: 'RULESET_TO_CLONE', 
  RuleSetName: 'TARGET_RULESET'
}

const command = new CloneReceiptRuleSetCommand(params);

client.send(command)

• Type definition of the credentials object
• Constructor definition of the CloneReceiptRuleSetCommand

You are referring only to the reference docs. To work with AWS SDK for JavaScript v3, refer to the Developer Guide:

AWS SDK for JavaScript Developer Guide for SDK Version 3

This guide contains the information you need to know to successfully work with this SDK. For example, to work and set your credentials, see:

Setting Credentials

Finally -- you can find many SES Code examples that use the AWS SDK for JavaScript in this Github repo.
