This is what I get any time I try to save any changes to any library.

[Req#167e] Errors in PUT request: Bad Request

400 Bad Request

‘agent’ is missing or invalid ‘language’ is invalid

3

Try disabling the support for IPv6 in the settings of Plex server.
Restart it, then try again.

4

Ipv6 was already turned off.

Tried again today and changes saved so I’m not sure what the issue was.

5

Issue is back. Can’t save any changes to any library. Trying to turn credit detection off for my home movies library. Get changes cannot be saved. Console has this error.

[Req#126b4] Errors in PUT request: Bad Request

400 Bad Request

‘agent’ is missing or invalid ‘language’ is invalid

Any time I save any change to any library that error shows up in the console and the change fails to save.

6

Just adding to this. I get the same error when trying to add a new library of any type also.

Have you tried to reload the web app in the browser?

8

Yes tried with both app.plex.tv and the localhost one.

Please enable debug logging in both server and client,
recreate the issue
then fetch logs both from server and web app.

Sorry, your web app log is empty.
Unfortunately, it is not usable for diagnostics.

12

Sorry about that, here is a populated log file

Can you confirm that this issue only occurs with libraries of the type “Other Videos”?

Which web browser type is used? It looks like CHrome, but the version number is not up-to-date, so I’m not certain.

14

For this test I tried to turn off credit detection on two “other video” libraries, but I get the same error when trying to make changes to any library type.

Browser used is Chrome 109.0.5414.122

Thanks for the logs!
I’ve filed a bug report.

17

Thanks! I did try with Chrome 110.0.5481.100 with the same result, just fyi.

18

Could you please stop and restart your server (with debug logging still enabled)?
This logging change is not executed until a server restart.
So most informations are unfortunately missing from your server log.
Please don’t forget to recreate the issue before fetching the server logs.

Well of course it is working this morning. I am able to save changes to my libraries now.

I did install beta server version 1.31.1.6716 yesterday so maybe that fixed it? I attached debug logs in the first post above the first time this happened if that helps debug.
