Backends provided no user object for Managers

[expert-geeks]

I'm testing duplicate finder for the first time and I'm repeatedly getting the following appearing in the nextcloud logs;

Error | files | Backends provided no user object for Managers

{"reqId":"XXX","level":3,"time":"2022-08-06T00:32:12+01:00","remoteAddr":"xx.xx.xx.xx","user":"user","app":"files","method":"GET","url":"/apps/duplicatefinder/api/v1/Duplicates?offset=0","message":"Backends provided no user object for Managers","userAgent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:103.0) Gecko/20100101 Firefox/103.0","version":"23.0.7.2","id":"xxx"}

After a great deal of time it returns;

0 duplicate file found

as you can imagine with 500k+ of office document files, I'm pretty sure there's some duplicates ;)

Running it from occ it gives this;

$ sudo -u www-data php /var/www/nextcloud/occ -v duplicates:find-all
