Plugin sync fails with 400 on /api/plugin/device and /api/plugin/import

[kama1509]

Description

Syncing via the KOReader KoInsight plugin fails with "no books and annotations found" / "server error" on the device. Server-side, the Docker logs show 400 errors for the relevant requests.

Setup

• KoInsight server: Docker (ghcr.io/georgesg/koinsight:latest), running on a Raspberry Pi
• Device: PocketBook Verse Pro, KOReader (latest version, plugin installed via AppStore)
• Server URL correctly configured and reachable (manual .sqlite upload via the web UI works fine)

Server logs during sync attempt

POST /api/plugin/device 400 109 - 2.135 ms
POST /api/plugin/import 400 109 - 3.590 ms

Expected behavior

The automatic sync should successfully transfer the statistics.sqlite3 data, the same way the manual upload does.

Additional info

Happy to provide further logs/details if needed.

Hey, in case you are still experiencing this, updating the docker image to ghcr.io/ko-insight/koinsight as mentioned in release notes, fixed the issue for me.
