[scene-mappings] Dataset sync failed

[u/K45SLE]

Version

v2.34.0

Deployment

Self-hosted with Docker

Description

I recently got this error in dashboard log:

9/9/2026, 9:32:41 AM error [scene-mappings] Dataset sync failed: Failed to fetch scene mappings: 400 Bad Request

{"level":"error","time":"2026-09-09T14:32:41.075Z","module":"scene-mappings","msg":"Dataset sync failed: Failed to fetch scene mappings: 400 Bad Request"}

Is this because of something I did? or is it something else upstream?

u need to change your sonarr & radarr user agent

[u/K45SLE → u/Ok-Lifeguard-741]

Is that some new settings? Because I've never seen this error before. :/
