[BUG]: Jellyfin.Api.Middleware.ExceptionMiddleware: Error processing request.

[Jiří Štefka]

The plugin doesn't let me sign in. All I get in the UI is an endless spinner (loading animation).
While looking into logs I noticed an error

Environment

OS: Docker
Jellyfin version: 10.9.0
Plugin version: 19.0.0.0
Host: Raspberry Pi 5
RAM: 8GB
Storage:

• Docker - SSD
• Media - HDD

Log

[02:55:57] [ERR] [81] Jellyfin.Api.Middleware.ExceptionMiddleware: Error processing request. URL POST /Jellyfin.Plugin.OpenSubtitles/ValidateLoginInfo.

Here's what the UI looks like:

Solutions I tried

1. Logging in again
2. Restarting Jellyfin
3. Reinstalling the plugin
4. Checking if the API is up
5. Deleting all Jellyfin configuration data and installing it again
6. Inputting my own API key
7. Changing my password (as mentioned in this comment)

Jellyfin 10.9 is not supported yet.

[Jiří Štefka]

Is there a way to allow plugin installation for only a specific version of Jellyfin? The plugin being displayed in the repo implies that it's working. If this is not possible I think that it's something to consult with Jellyfin - I'd make an issue for it.

Would be way better UX.

[Cody Robibero]

No, that is not a feature Jellyfin has.

This is still happening in 19.2403.7.0, which is supposed to work with 10.9 as far as I understand?

[Cody Robibero]

Yes, the unstable plugin should work with unstable server. If it is not please create a new issue.

[Jiří Štefka]

@Simsala91 Your issue is probably resolved in #115.

Build yourself the plugin if you need the plugin now or wait some time until #115 is merged and published to the unstable repository.

@jiriks74 Thanks for the response, mostly wanted to make sure everything is working as expected once 10.9.0 actually releases :)

I get that. Sadly I have to use 10.9 since 10.8 has quite some issues with my RPi5 which 10.9 doesn't. Like scrubbing through the film, it takes a longer time until the film loads, the transcoding is slower...

Some of the issues may be related to the docker image as 10.9 has probably newer dependencies with better support for 10.9
