It would make sense to limit the exception clause a bit. You can inspect botocore exceptions by catching CommonServiceException and then checking e.code for the particular error code.

Do you have an example of that exception handle practice?

in most cases you can simply pass through the exception and don't need to do anything. if moto raises a NotFoundException, then call_moto will re-raise something that is equivalent and will be rendered correctly.

here's an example where we inspect the exception and re-raise them conditionally. not sure that's your use case though

I guess it makes sense depending on the case, as we talked in private is not applicable in this case.
