is your library Read Only? i noticed if its RO i get an error

[TheBlueKingLP]

Where do I check if the library is read only? If you mean the file system the library is in then no, jellyfin can write to it.

Are you running docker ?is your media library lets say its "tv" & "movies" read/write permissions on the mapping side?

What platform are you running JF?

[TheBlueKingLP]

My library is mounted with write enabled. Platform information is stated in the original post. Thank you.

Ive just installed this plugin, it seemed to be working at first until i noticed it was only working on a test library, i deleted the test library & now i have an error basically the same as this. Tried setting my mounted media folder to read/write but didnt make a difference. Unfortunately at this stage this plugin does not work for me. Seems very cool though, would love to help resolve the issue.

I had the same error, and it seems like triggering the library scan before fixed the problem. Can you try ?

[Terror-Gene]

Working now, but I did a few things after my post, so cant be sure as to the remedy. pretty sure i had scanned my library before i had the issue, but i did realize that my main TV Shows library had an additional old directory in it which didnt exist anymore, could have contributed to the issue. I ended up removing my library & creating a new one (library was made ages ago & i suspect it was harboring some outdated stuff, breaking things (i couldn't save after editing any library settings)). after recreating the library & finishing a scan it seems that Intro-Skipper is now processing everything as expected.

Just wanted to say this fixed the issue for me. If the scanning of the library fails, then check the permissions.
