[Bug]: Appstore catalog fetch throws InvalidArgumentException and breaks entire Apps page when an app ID exceeds 32-char AppConfig column limit

[lmargit]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

Loading Settings → Apps → Updates (and likely other Apps subpages that fetch the remote catalog) fails completely with "Could not load apps list. Please try again later." The root cause is an uncaught InvalidArgumentException thrown while iterating the full remote App Store catalog to check each app's enabled/disabled config state. One catalog entry, skynettechnologiesallinoneaccessibility (40 characters), exceeds the 32-character limit enforced by OC\AppConfig::assertParams() for the app parameter.

Steps to reproduce

1.Go to Settings → Apps → Updates (or any Apps category page that triggers a fresh catalog fetch)
2. Observe "Could not load apps list. Please try again later." with an empty list, even though updates may genuinely be pending elsewhere
3. Check nextcloud.log for InvalidArgumentException: Value (skynettechnologiesallinoneaccessibility) for app is too long (32)

Expected behavior

The Apps page should load successfully regardless of malformed/oversized app IDs in the remote catalog.

The name app name skynettechnologiesallinoneaccessibility is with 37 characters above the set limit of 32 characters.

For those running nc 34+ in a docker - here the patch:

docker exec -it nextcloud_app sed -i ‘s/private const APP_MAX_LENGTH = 32;/private const APP_MAX_LENGTH = 64;/g’ /var/www/html/lib/private/AppConfig.php

clear the error cache

docker exec --user www-data -it nextcloud_app php occ config:app:delete core appstorenotavailable

and restart your docker container

But remember - just a patch - no fix!!!
