Error detecting ES by FTS 20.0.0

[Ark74]

Hi, happy 2021,

Today I just upgraded and found out that using,

• Nextcloud 20.0.4
• FTS - 20.0.0
• FTS FIles - 20.0.0
• FTS ES - 20.0.0

It has issues detecting Elastic Search for some reason, the error occurs on https://github.com/nextcloud/fulltextsearch/blob/master/lib/Service/PlatformService.php which is not part of fulltextsearch_elasticsearch, @daita should I move this somewhere else?

$ php ~/occ fulltextsearch:check

I'm a little emberassed to say but just want to add the solution here in case it helps anybody: Go to your nextcloud website, "options - full text search" . For me, it was just disabled. When I clicked the "plattform" selector and chose "Elasticsearch", it did remember my old settings and immediately, it worked.

Hi @IFM-Ulm , somebody in https://help.nextcloud.com/t/fulltextsearch-does-not-work-after-update-to-nextcloud-20/95569/9 found out that the spelling of the platform name changed from ElasticSearch to Elasticsearch. Maybe the migration path did not consider this change.
