I've never seen a null path appear.

I can think of 4 scenarios:

1. You do have a duplicate file and it's a problem with this script. Can you find out what's going wrong? see what you have in $DUPE after line 120. Maybe the Jellyfin API gives the path information on a different key in some circumstances. Is there anything special about how your library is set up?
2. You do have a duplicate file but the Jellyfin API isn't providing the path for some reason. See what you have in $DUPE after line 120 to verify, and maybe it's something we raise to the Jellyfin developers.
3. You don't have a duplicate file, and the Jellyfin API is doing nothing wrong, but this script has produced a new row through some bug. Can you help debug? What was in $DUPES after line 115?
4. You don't have a duplicate file, but the Jellyfin API is giving an entry it shouldn't. This seems like a bug on the Jellyfin side, whether it's choking on something wrong in your library or not. What is in $DUPLICATES_JSON after line 111?

I'll need your help on any of these since I can't replicate this issue on my end.

What happens to me is that I upload a video file in one format to an episode, then delete the video file, and at the same time upload a video file in another format (with a different filename). If you upload the second version first and then delete the first one, it will also happen.

Does the null clear away if you tell jellyfin to update your library?
