watermark & anonymous users

[gadkin]

If watermarks enabled, anonymous users cant open files in nextcloud on shared links. Logged in users can open files normaly.
Error in logs:
Exception OCA\DAV\CalDAV\TimezoneService::getUserTimezone(): Argument #1 ($userId) must be of type string, null given, called in /var/www/nextcloud/apps/onlyoffice/lib/Controller/EditorApiController.php on line 846 in file '/var/www/nextcloud/apps/dav/lib/CalDAV/TimezoneService.php' line 28

As workaround i edited line 846 in EditorApiController.php:
was
$timezone = $this->timezoneService->getUserTimezone($userId) ?? $this->timezoneService->getDefaultTimezone();
edited
$timezone = $this->timezoneService->getDefaultTimezone();

OO connector ver 9.5.0.
