Friendica: Error 500 on .../admin/workerqueue

[AlfredSK]

Expected behavior

When I click on the right queue indicator in the admin panel the page .../admin/workerqueue should be loaded with a HTTP code 200.

Actual behavior

I get a white screen of death with HTTP code 500.

Well, click on the (relatively) new link or open https://yournode.frnd/admin/workerqueue directly.
