Issue with Lambda Hook Not Receiving Endpoint Details When Creating AWS Campaign

Hello AWS Community,

I'm currently facing an issue while creating a campaign on AWS from JS SDK. Specifically, when utilizing a Lambda hook in the process, it seems that the Lambda function is not receiving endpoint details in the argument.

I've checked the Lambda function configuration, ensured proper permissions, and implemented logging for debugging. However, the problem persists. Could someone guide me on how to troubleshoot this issue effectively?

If anyone has encountered a similar problem or has insights into Lambda hooks during campaign creation, I would greatly appreciate your assistance.

Thank you!
