After the update to Nextcloud 20 and fulltextsearch 2.0 I’m getting the following errors when searching:

Error: Undefined offset: 1 at /var/www/html/custom_apps/fulltextsearch/lib/Search/UnifiedSearchProvider.php#158
Error: Array to string conversion at /var/www/html/3rdparty/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOStatement.php#81

Also the fulltextsearch:search command throws this error:

An unhandled exception has been thrown:
TypeError: Argument 1 passed to OCA\Files_FullTextSearch\Service\FilesService::getFileFromId() must be of the type string, null given, called in /var/www/html/custom_apps/files_fulltextsearch/lib/Service/SearchService.php on line 269 and defined in /var/www/html/custom_apps/files_fulltextsearch/lib/Service/FilesService.php:463

Does anyone have the same problems and how can I solve this?

  1. Did you follow the documentation for proper installation?
  2. Check their github repository.
3

Yes I followed the instructions and also searched for this error on GitHub, but didn’t find anything. I’m not sure which version of elasticsearch is recommended. I tried several versions from 6.5 to 6.8. 6.7 seems to be the minimum version go get the index to run at all. Do I maybe need elasticsearch version 7?

4

Elasticsearch is actually available as a separate app in the appstore. Mentioned in documentation here.

5

I know that and I’ve already installed the app, but there is still an installation of elasticsearch required as described in the wiki on GitHub. I now also tested elasticsearch version 7.9.2, but I’m still getting the same errors. Any other ideas?

Update: I just found out that the fulltext search works if I enable the search as a navigation item and search there. But If I search using the search function on the top right I get those errors. Also the fulltext search does not work in the Android app.

6

Gotcha, I recommend filing bug reports to the app and android client. Bummer.

7

There are a few bugs with upload and download. With deactivating the app “activities” these problems can be solved. Perhaps you can test it also for your problem.

8

The Activities app is active on my installation. I’m still having this problem in version 20.0.4. I’ve also created a comment in this issue on GitHub, but did not receive an answer yet. Does no one else have this problem?
