Describe the Bug

After upgrading from v22.02.3 to v22.06.01 almost everything in our Bookstack instance returns "An unknown error occurred". All shelves/books/chapters/pages are also missing.

I can still se my groups on my user profile but that is pretty much it.

I have rolled back our instance to a snapshot now but if needed I can upgrade again for further troubleshooting.

Steps to Reproduce

Upgrade to v22.06.01 using git version control
Login to Bookstack - the landing page displays "An unknown error occurred".

Expected Behaviour

Bookstack should function normally and return shelves/books/chapters/pages with no errors.

Screenshots or Additional Context

Browser Details

Exact BookStack Version

22.06.01

Hosting Environment

Hi @GustavJer,
You will need to check your error log to find the cause of this error:
https://www.bookstackapp.com/docs/admin/debugging/#error-log-file

Based on your description, it's likely that some required database changes have not been applied.
Were there any issues when running the php artisan migrate step of the update instructions?

Hi @ssddanbrown

I reran the update again and this time it went fine :)

Tho I noticed the same problem with the LDAP group mapping breaking which was already mentioned in #3535.
