Fulltextsearch shows error when searching on CLI, works perfectly in Web UI

[e-alfred]

My system is running Nextcloud 16.0.1 with the latest Fulltextsearch apps and Elasticsearch 7.2. I indexed everything successfully, but if I try to search anything the following error is thrown:

# sudo -u www-data php occ fulltextsearch:search user linux
search
An unhandled exception has been thrown:

I am also getting this if I run the command without any arguments:

sudo -u www-data php occ fulltextsearch:search
search

Interestingly, the search using the Web UI works perfectly fine without any errors.

elasticsearch 7.x IMHO not works, use 6.7

Searching through the Web UI works perfectly actually using 7.2, this bug appears only on the CLI using the occ command. The error happens even before any search is started on the Elasticsearch instance, it seems that the UID isn't correctly fetched on the Nextcloud server by the occ command.

Confirming that this isssue is still valid with Nextcloud 20.0.4 and the Fulltext-Search Apps in Version 20.0
