Description of the bug

I'm managing Demon Slayer: Kimetsu no Yaiba in Jellyfin, but I found that the metadata for several episodes is not displaying correctly. When I attempted to manually fetch and overwrite the metadata, I encountered the following error in the logs.

Reproduction steps

Find a TV show on TMDB that has missing actor names in its data. Then try to fetch its metadata.

What is the current bug behavior?

When an actor's name is missing, the entire metadata for that episode fails to load properly.
In my case, the problematic actor is: https://www.themoviedb.org/person/2868405?language=zh-CN — their name is missing in the Simplified Chinese metadata on TMDB.

What is the expected correct behavior?

Discard the invalid data for individual actors, or allow empty names, instead of letting it prevent the rest of the episode's metadata from being retrieved.
