Jellyfin NextPVR Plugin Recording Requests Fail - JSON Parsing Error

[JustMeNZ]

Disclosure: After utilising Claude AI for help, AI provided the info below.

Setup:
Jellyfin: 10.10.7
NextPVR Plugin: 11.0.0.0 (also tested with 10.0.0.0)
NextPVR: 7.0.1.241229
Platform: Windows
IPTV setup with comskip and ffmpeg working perfectly

Problem:
this affects both single and series recordings. Live TV viewing through Jellyfin works perfectly. Recording directly in NextPVR works perfectly. However, ALL recording requests from Jellyfin (both single episodes and series recordings) fail with a spinning wheel and never complete.

Jellyfin logs show:

Code:

[ERR] Jellyfin.Plugin.NextPVR.LiveTvService: Failed to create the timer with programId: "1323459"
[ERR] Jellyfin.Api.Middleware.ExceptionMiddleware: Error processing request. URL "POST" "/LiveTv/Timers".
System.Text.Json.JsonException: Failed to create the timer with programId: 1323459

NextPVR logs show:

Code:

[DEBUG] Got request [127.0.0.1]: /service (recording.recurring.save)
[DEBUG] parameters:
[DEBUG]    method: recording.recurring.save
[DEBUG]    event_id: 1323459
[DEBUG]    recurring_type: 2
[ERROR] neither event_id or start_time/end_time specified
[DEBUG] {"stat":"Failed","code":2,"msg":"Invalid Args."}

The Jellyfin plugin is incorrectly calling recording.recurring.save for ALL recording requests (including single episodes), when it should use recording.save for one-time recordings. NextPVR rejects this with "Invalid Args", but the plugin tries to parse the error response as success JSON, causing the JsonException.

Troubleshooting Completed:
- Verified NextPVR recording works directly
- Verified live TV works perfectly in Jellyfin
- Set PIN code (0000) in both NextPVR and Jellyfin plugin
- Enabled "Allow unauthenticated access" in NextPVR
- Tested both plugin versions 10.0.0.0 and 11.0.0.0
- Multiple Jellyfin/NextPVR service restarts
- Verified NextPVR web service accessible on port 8866
- Confirmed recording directories are writable
- Tested different shows and channels
- Verified authentication working (live TV streams successfully)

NextPVR Settings:
NextPVR > Settings > Access: PIN set to 0000
Web server enabled and accessible
Both authenticated and unauthenticated access tested

This appears to be a bug in the NextPVR plugin where it's using the wrong API method for single recordings. Is there a configuration option to force the plugin to use the correct recording.save method instead of recording.recurring.save? Or is this a known issue with a fix in development?

Looking for a permanent solution to enable Jellyfin as a complete one-stop live TV and recording solution for family use.
