def do_something(input_data: str) -> str:

this will break its execution using the new

The problem is in typing.get_type_hints() function - it will return return as one of type hints:

>> typing.get_type_hints(do_something)
{'input_data': <class 'str'>, 'return': <class 'str'>}

What will be wrongly interpreted by as a required argument for operation:

We need to add an exception to the return hint to skip it.
