				rohan-sachanUnsubmitted Not Done Inline Actions Getting the following error. It's because the BaseMapping base class in base.py doesn't have supperted_terms() fucntion. Although right now none of the metadata indexers are implementing BaseMapping class directly. One resolution is to just ignore the [attr-defined] and [arg-type] errors on line 23 and 24. If there's another way round, then please let me know. __init__.py:23: error: "Type[BaseMapping]" has no attribute "supported_terms" [attr-defined] __init__.py:24: error: Argument 1 to "add" of "set" has incompatible type "Type[BaseMapping]"; expected Module [arg-type] rohan-sachan: Getting the following error.

				vlorentzAuthorUnsubmitted Not Done Inline Actions Instead of using `# type:ignore [attr-defined]`, you should add `supported_terms()` to the definition of `BaseMapping`. That way, mypy can actually check types are ok. vlorentz: Instead of using `# type:ignore [attr-defined]`, you should add `supported_terms()` to the…
