Updated to Nextcloud 16 An unhandled exception has been thrown:

[Omaha2002]

After updating Nextcloud 15.0.7 to 16.0 I found out that results from one groupfolder didn't show up anymore so I decided to reset and reindex database.

[syntron]

I just tried to install elasticsearch on NC16 and got bitten by the same error ... latest versions of all NC apps + Elasticsearch 6.7.1

[Omaha2002]

It is the deck app that causes this. Disabling it will make indexing work.

[syntron]

@Omaha2002 Thanks for the hint! I can confirm that it is working if Deck is disabled.

[Omaha2002]

Well, for me it still crashed at the end of indexing:

f:first error ## h/j:prec/next error ## d:delete error ## l:last error

@Omaha2002 I will need some time till I come to this point; at least I could start it here ...

[truelai]

Same issue here. Disabling Deck fixes the issue. The problem is I need both Deck and FTS.

Didn't this Deck/FTS conflict happen a month ago as well?

[ArtificialOwl]

Anyone willing to test this fix on Deck ? : nextcloud/deck#1049

I'll give it a shot.

[truelai]

The patch seems to work.

Documented in #498

for me it doesn't, Deck 0.6.2:

@Omaha2002 did you apply the patch ?

[truelai]

@Omaha2002 I used the Deck patch provided by @daita. Can you post the contents of your file here?

/var/www/nextcloud/apps/deck/lib/Service/FullTextSearchService.php

[Omaha2002]

I'm sorry guys, I didn't use the patch, I thought the updated deck would fix the problems. I'll try later this weekend.

[syntron]

I can confirm that the patch is working; I changed the two lines manually and now Deck is activated and fulltextsearch index is running

[Omaha2002]

I can confirm that the patch works too regarding Deck. Changed lines manually too and with Deck activated fulltextsearch index is running but exits with an error. I think it's another app that causes it:

[drpetersen]

I get this error (Call to a member function getUID() on null in /var/www/nextcloud/lib/private/Share20/Manag er.php:1433) as soon as indexing hits the first document shared to the user whose files are being indexed. When I revoke that share and restart indexing (occ fulltextsearch:stop; occ fulltextsearch:index), indexing can go further, that is, until the next (incoming) shared document is reached. Maybe this helps finding the source of the error?
Edit: By the way, this is with the deck app disabled.
