ref(aci): Remove a try/except block for more detailed errors (#111439)

# Description
When investigating an issue, it was difficult to determine the source of
the issue because we hit the exception block and lost which of the
ValidationError was bubbling up.

This will just allow the more specific validation error to bubble up and
reformat them to all be ValidationErrors that can be handled in the API.

The code still catches the exception and retriggers it to ensure the
control flow is consistent and the validation error types are correct.
