After the last update of Kimai its not lomger possible for me, to sync the app on my iPhone withe the server. I can connect the app, but i dont get data. I found this in the logs:
2025-11-18T17:45:13+01:00 [1:kimai1:kimai-app] [2025-11-18T16:45:13.740389+00:00] request.ERROR: Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\BadRequestHttpException: “Size must be between 1 and 500” at BaseApiController.php line 89 {“exception”:“[object] (Symfony\\Component\\HttpKernel\\Exception\\BadRequestHttpException(code: 0): Size must be between 1 and 500 at /opt/kimai/src/API/BaseApiController.php:89)”} {“channel”:“request”}
this seems to be some bug in kimai itself, you could open an issue at the kimai github page. I checked the issues but didn’t find a similar error.
I tested the downgrade to the previous Kimai version 2.40.0 (app version 1.0.12) and it worked so I hope that’s a workaround until the issue is fixed.
To downgrade: (please run a backup before to at least have the data if something goes wrong)
Just adapt “kimai1” to your Kimai instance name.
api-cli run update-module --data '{"module_url":"ghcr.io/mrmarkuz/kimai:1.0.12","instances":["kimai1"],"force":true}'
EDIT:
Hello @transocean, a new Kimai version 2.44.0 was released, maybe it fixes the issue, it’s available in Software Center as Kimai app 1.0.14.
A downgrade to 1.0.12 in case it doesn’t work is also possible.
Unfortunately, the update does not change anything. I tried uninstalling and reinstalling the app from my mobile phone. That didn’t work either. Resetting to version 1.0.12 was successful.
