Bug description

I have an instance running on Azure VM where I run NC 33.0.2. Which is using for authentication SAML SSO plugin 7.1.4 and when I use the top right corner global search it never finds anything and just stops at showing the Searching ...

I tried to enable debug but nothing interesting is in the log nextcloud.log nor PHP. I'm not sure how to troubleshoot this further.

Browser console shows that there is a call for POST https://nc..com/index.php/contactsmenu/contacts 500 (Internal Server Error) for some earson and then Error from unified-search

ERROR] unified-search: Unexpected AxiosError "Request failed with status code 500" {app: 'unified-search', uid: '@', level: 0, error: AxiosError: Request failed with status code 500
at r (https://nc..com/dist/core-common.j…}

I was trying ocs/v2.php/search/providers but there is no contacts provider. And those listed which finish with 200. It used to work but I'm not sure now when this broke.

Steps to reproduce

1. Click in the Search
2. Put there anything
3. The error appears in the browser console but there is nothing in the server logs

Expected behavior

The Search should show a file if it exists or tells me it does not.
