[BUG] Last job execution ran 3 months ago. Something seems wrong.

Is there an existing issue for this?

Current Behavior

Background cron job seems to be failing to execute. Noticed a "Last job execution ran 3 months ago. Something seems wrong." warning in Settings->Administration->Basic Settings. Docker logs show the following error every 5 minutes, which I've replicated by running the command directly

root@5890e035c019:/# s6-setuidgid abc php -f /config/www/nextcloud/cron.php
TypeError: OCA\Files_Reader\Hooks::OCA\Files_Reader\{closure}(): Argument #1 ($node) must be of type OCA\Files_Reader\Node, OC\Files\Node\Folder given in /config/www/nextcloud/apps/files_reader/lib/Hooks.php:18

#10 {main}

Expected Behavior

Background jobs are executed by cron every 5 minutes without errors.

Steps To Reproduce

This is a long running instance, so reproduction might be a tad difficult, but:

1. Create container (see Docker Compose File, below)
2. Periodically update the container, and run docker exec -it nextcloud updater.phar
3. Eventually, notice error in nextcloud admin panel
4. Exec into the container, and run s6-setuidgid abc php -f /config/www/nextcloud/cron.php (taken from the cron file)

Environment

- OS: NixOS 22.05 (Quokka) x86_64
- How docker service was installed: Nix Package

CPU architecture

Unfortunately, this seemingly related issue (very old) was closed without investigation.

This seems to be specific to https://apps.nextcloud.com/apps/files_reader ( Yetangitu/files_reader#1 )

There could be a missing dependency, or the app could be trying to use a php function that does not work in php8. There doesn't seem to be much documentation on the issue, but it's not something we have control over within this repo.

Re: #48 we didn't have enough info to troubleshoot (ex: the logs included here) but it was probably something similar (although maybe not the same app, but likely a compatibility issue with either the version of nextcloud or the version of php).

The two things I could recommend would be to either:

• uninstall the app (safest option, but you would be without the functionality the app provides - maybe comment on the GitHub issue linked above and see if the dev can address the problem)
• roll back to a previous version of our image that includes php7.4 (no guarantee this will fix the issue)

I would NOT recommend (and we have no way to support) downgrading nextcloud.

I'm going to close this issue, but if there is new information that could require a change in our container (ex: it is found that we need to supply a particular dependency) please feel free to comment.

Disabling the app fixed the problem, thanks! Didn't even connect "Files_Reader" with the Ebook Reader app.

And no shade intended with the comment about the prior issue, just wanted to make sure it was linked.
