How do I notice that a file executed from AWS StepFunctions has stopped?

Question

SendCommand is executed in AWS StepFunctions.

I am executing a file in EC2 from SendCommand.

If the file stops in the middle, I want StepFunctions to exit with Fail Status.

How can I achieve this?

Answer 1

You have to use Callback with the Task Token. Your application on ec2 has to "know" when it succeeds or fails, and send SendTaskSuccess or SendTaskFailure to Step Functions.
