Hello,

I’m using the files automated tagging app since a few months now.
App version: 1.6.0
NC Version 16.0.1

For some reason I wanted to rescan all the files contained in the cloud, so I issued sudo -u www-data php occ files:scan --all. After the process was running for a while, I got following error:

Exception during scan: An exception occurred while executing 'SELECT * FROM "oc_systemtag" WHERE "id" IN (?) ORDER BY "name" ASC, "visibility" ASC, "editable" ASC' with params ["12"]:

I’ve tried to figure out the problem. It seems that the files automated tagging app breaks occ:scan command.

My instance is running on PostgreSQL. I set up a new instance with MariaDB and there I wasn’t able to reproduce the problem.

GitHub issue is here, but no response within a few days: https://github.com/nextcloud/files_automatedtagging/issues/75

My question is now if someone can confirm that this is a problem related to PostgreSQL or if it is a general problem.

Thanks in advance!

Can confirm this behaviour.

Using NC 18.0.1 with PostgreSQL 12.2
At first thought that PHP 7.4 is the problem so switched back to 7.3.14

After a second run of occ files:scan --all same errors occur.
I disabled files_automatedtagging and error went away.

I never had this errors with NC 17.0.3 in combination with PostgreSQL 12.2 and automated tagging enabled.
So can’t imagine that it is a PostgreSQL Problem…

Since 18.0.1 another failure is obvious concerning tagging! I can’t tag files or folders manually as well. Not with php 7.4.2 nor with 7.3.14

So in my opinion it is a serious bug in NC 18.x that should highly be examined.

The button for tagging is functionless since tagging has been switched to the three dots menue under NC 18

Very very bad because i need tagging in combination with files_accesscontrol and files_retention
