Thank's for reporting this. I also saw these messages on my dev machine but I thought they are related to some test data I created earlier. Will try to dig deeper into that ASAP.

@robsmy98 I think I found a fix for that. Would you mind testing the current patch from https://github.com/R0Wi-DEV/workflow_ocr/suites/15285716874/artifacts/872905928 ?

I could try it in one week, thank you in advance :) Robin Windey ***@***.***> schrieb am So. 20. Aug. 2023 um 22:17:

That seemed to work for me.

I had the same issue for a single file, single user.

Before Patch:

After Patch:

Much better! To solve the actual issue, I had to ssh into the DB and delete the offending entry from oc_jobs. Hopefully that helps the next person getting spammed in the logs.

Thanks for your feedback @farhills! Even though I could not reproduce this behaviour after the patch, I added a migration step which should remove the pending Notifications when upgrading to the next app version.

Fix will be shipped with v1.27.2
