Hey folks, first go with Hamilton. A toy example using a file-loading function with this signature works fine:

def some_df(file_path: str, config: Dict[str, Any]) -> pd.DataFrame:

"""Read a file from a folder."""

But the following tiny change

D

->

d

in dict:

def some_df(file_path: str, config: dict[str, Any]) -> pd.DataFrame:

"""Read a file from a folder."""

yields a perplexing error.
