Two errors with new dev branch

I am at commit d68bc0189677f79a34185de53e0610274e7243c4 (HEAD -> dev, origin/dev)

    feat: "treat_as" default to be "config", "path" default to be function name
    example: remove Optional, empty decorator

But when I tried to convert examples/examples.py, I ran into two errors:

  File "/home/forrest/Textea/PyDataFront/examples/examples.py", line 116, in <module>
    def calc_literal(a: List[int], b: List[int], op: Literal["add", "minus"]) -> calc_return:
  File "/home/forrest/Textea/PyDataFront/backend/pydatafront/decorator/__init__.py", line 173, in decorator
    decorated_params[function_arg_name].update(function_arg_type_dict)
TypeError: 'NoneType' object is not iterable

    def calc_add(a: List[int], b: List[int]) -> calc_return:
  File "/home/forrest/Textea/PyDataFront/backend/pydatafront/decorator/__init__.py", line 222, in decorator
    get_wrapper(decorated_function_param_getter)
  File "/home/forrest/.local/lib/python3.10/site-packages/flask/scaffold.py", line 440, in decorator
    self.add_url_rule(rule, endpoint, f, **options)
  File "/home/forrest/.local/lib/python3.10/site-packages/flask/scaffold.py", line 56, in wrapper_func
    return f(self, *args, **kwargs)
  File "/home/forrest/.local/lib/python3.10/site-packages/flask/app.py", line 1090, in add_url_rule
    raise AssertionError(
AssertionError: View function mapping is overwriting an existing endpoint function: calc_add_param_getter

I am not sure whether this is due to that the example functions have not be refactored to be compatible with the latest PyDataFront decorator in the dev branch.

You might run into merge conflict or another type of conflict with two functions with the same path.

I could run the backend with dev examples. A screenshot is attached below.
