Pydantic Validation Error for LineStats

[GinFizzz]

This exception doesn't really specify which field is actually too short, nor where the field is discovered, just that it fails the pydantic check.

Any chance there's a way to either improve the info given or get info on how to work around this?

Hi @GinFizzz
It comes from this line

    file_name: str = Field(..., min_length=1, description="File containing this line")
    function_name: str = Field(

link to code

Do you have an idea of why you would have a file_name equal to "" ?

If there are valid reasons for you to have a file name of lenght 0, maybe we should remove this pydantic validation then.
