Steps to reproduce

1. Install this app in a Nextcloud 31 environment (I used Docker - nextcloud:31 image).
2. Upgrade to Nextcloud 32.
3. Observe that the OpenID Connect user backend app and all settings are missing in my list of apps and the admin page. It is also missing when I search for the app to try and install it.
4. When I attempt to login to NC it asks me for a user and password, so I can only login with my local admin account. No OIDC is attempted or offered. My configuration in NC 31 is to automatically use OIDC so I don't even have to click a button, it just automatically forwards to my IDP.

Expected behaviour

The expected behavior is that I should be able to continue using my configured OIDC provider, which happens to be authentik.

Actual behaviour

Instead, all traces of this app and its configuration are completely missing. I had to roll back to my preupgrade backups to be able to get it working again. There are 0 related logs to this app when I look in the Logging section under the Admin page.

I was looking through the upgrade docs and saw that it said this: If AppAPI is disabled, other apps that depend on it will not be visible in the app store. Does this app require AppAPI? I wonder if that is why?

Any other ideas on why this would be breaking would be much appreciated. For now I am stuck on unsupported NC 31 and would like to upgrade to NC 32 as soon as possible.

Thank you so much for any help!

Nextcloud configuration

The below output is from before I upgraded (meaning it's from my NC 31 instance). I had to roll back and don't want to upgrade into a broken state again until I have something else I can try. I suspect it will be nearly the same though, with just a slightly different version.

N/A - No relevant logs that I could find. Let me know if there is anywhere else I can check other than the Admin > Logging, Docker logs, and browser logs.

Insert your browser log here, this could for example include:
a) The javascript console log
b) The network log

Thank you for reporting this.
Is there a chance the user_oidc app directory has been deleted during your upgrade?
How do you handle extra/custom apps? Are they installed in the same directory as the shipped apps (like files, dashboard, comments etc...)?

So you're saying once you upgrade, the app is gone (i guess it is either disabled or its directory has been deleted). And you don't find it in the apps settings, right?
Have you tried running occ app:install user_oidc?

I was looking through the upgrade docs and saw that it said this: If AppAPI is disabled, other apps that depend on it will not be visible in the app store. Does this app require AppAPI? I wonder if that is why?

It does not depend on AppAPI.
