The Error log entry is: Errors in PUT request: <html><head><title>Bad Request</title></head><body><h1>400 Bad Request</h1></body></html>'agent' is missing or invalid new scanner needs to be paired with new agent

How did you arrive here?

Was this a library using the old “Plex Movie” Scanner and “Plex Movie (Legacy)” Agent?

Did you choose Upgrade Matching on the Library?
Or did you manually change the scanner and agent in the Library settings?

I didn’t change any agents prior to doing this. I just saw “Upgrade Matching” under “Manage Library”. I presume it only shows if it needs upgrading? I haven’t upgraded before.

Going into the Library view now it says it’s using “Plex Movie (Legacy)” with the “Plex Movie Scanner” scanner.

Upgrade seems to work fine now on 1.20.2.3343.
