Additional Context
The error disappears and the command works by adding

    if not genres:
        return ""

below def conv_genre_format(genres: list[str]) -> list[str] | str: in utils.py of Zotify, didn't bother to investigate more of the code as the simple solution worked.

Good catch. I fixed this in efficient-api and didn't backport it.
