I have same problem. Ubuntu 18.04 NC 15.0.0

[pfaelzerchen]

I had the same problem with Nextcloud 15 and ElasticSearc 6.5.3 (both with docker). Release 1.2.3 fixed it for me. Indexing ran fine and searching files works.

Issue seems to be solved.

Issue seems to be solved.

Sorry, but not
Error can be reproduced only if "GroupFolders" app enabled
Disabling Group folders app allow create index

[ArtificialOwl]

You might need to reset your index

Same here. Using last files_fulltextsearch with nextcloud 20.0. I have to disable "GroupFolders" to get the index correctly working.
