Unhandled Exception getOwner() on null

[fwolfst]

On NC 21.0.1 with elasticsearch 6.8.8 and fulltextsearch: 21.0.0 with fulltextsearch_elasticsearch: 21.0.0, where the fulltextsearch is a fresh installation, occ fulltextsearch:index throws an error after a while of happy (and a bit of unhappy -> errors) indexing.

I am happy to tinker and help debugging and am not afraid of running some SQL queries to get to the bottom of the issue, but are not familiar with the codebase. Any idea what is wrong?

An unhandled exception has been thrown:
Error: Call to a member function getOwner() on null in /var/www/nextcloud/lib/private/Share20/Manager.php:1646

Okay, this seems to happen when "index groupfolders" is set to yes, groupfolders exist, but the groupfolders plugin is not activated.

Still, this code path might get called from other places, any idea where to file this issue "upstream", in the correct repo? I will close the issue here and reopen it in the correct place if I get any pointers. (Update It happened again, with groupfolders plugin enabled)

Same error here, unfortunately. Groupfolders exist and are enabled

[Omaha2002]

Same error, also Groupfolders exist and enabled. Tried indexing with and without groupfolders indexing selected
