Doesn't seem to make any trouble (didn't see any issue using the social app) but it makes the log very much full !

[edit] It was fulling the log too much, I had to disable the Social app. I'll wait for a fix before enable it back.

[rikmeijer]

Fixed (well, it stopped generating errors) it by replacing line ./apps/social/lib/AppInfo/Application.php@71 with:

$dispatcher = $this->getContainer()->query(IEventDispatcher::class);

and adding (at the top of the file)

use OCP\EventDispatcher\IEventDispatcher;

(based on https://docs.nextcloud.com/server/19/developer_manual/app/events.html)

[Thatoo]

@rikmeijer did you make a PR for that?

[Thatoo]

Could you write which line you modify and replace by $dispatcher = $this->getContainer()->query(IEventDispatcher::class); ?
because line 71, I have
71 $this->registerDeprecatedListener();
and it doesn't feel right to make the modification there. If you had said to change line 82, I'd understand better :
82 $dispatcher = \OC::$server->getEventDispatcher();

[rikmeijer]

I put my altered Application.php in a gist

[paulcalabro]

Thanks for sharing that @rikmeijer ! That appears to have resolved the issue for me.

[paulcalabro]

Is anyone working on this? If not, I can make a PR.
