Impossible to use get_type_hints in main file

[ChristianSauer]

get_type_hints is used by Pydantic, dacite etc. to create their model classes, so it'S kinda important.

Currentliy, this is broken in main.py:

Traceback (most recent call last):
  File "***\main.py", line 40, in ar_v4
    data = dacite.from_dict(RequestData2, message)
  File "***\venv\lib\site-packages\dacite\core.py", line 43, in from_dict
    data_class_hints = get_type_hints(data_class, globalns=config.forward_references)
  File "C:\dev\python3.8\lib\typing.py", line 1220, in get_type_hints
    base_globals = sys.modules[base.__module__].__dict__
KeyError: 'main'

reproduction:

install dacite
in main.py

import dacite
import dataclasses

@dataclasses.dataclass
class RequestData2:
    product_number: int

def hello_world(request):
    message = request.get_json()
    data = dacite.from_dict(RequestData2, message)
    return ""

post some data to it and observe the error.

Workaround:

create another file and place your data classes in them

Thanks for the bug report! This is fixed in functions-framework==1.4.3.
