Lambda Invoke -- Error handling and Retry for Throttles within Map

Question

Hello,
I am looking for help in how to set error handling in the AWS step function's workflow studio. In particular, I am looking for how to set retries for a lambda function within a distributed map to handle throttles. I appreciate it if someone could help me with figuring out the different parameters in  "Add New Retry". 
Two specific questions
1, What error I should select for Throttles?
Errors
Specify one or more error(s) that will trigger this retrier. You can select a built-in Amazon States error or enter a custom error name.
2. Do I need a "Catch"

Thank you in advance!

Answer

Hi 👋🏽

which throttle exception do you want to catch exactly? How I do this normally is by trying to get the exception triggered (if that is feasible) and using the error name or type then.

How I did that in the past is by having a catch on all errors and then a choice state for specific error types.

Sorry I needed to blur a few things. Does that help?
