Describe the bug

Somewhere between 1.2.16 and 1.2.20, non device based data sources (Device: None) stopped being polled (no data collected and does not show up in the poller cache). It worked in 1.2.16 and older, it does not seem to work after upgrading to 1.2.20 (and 1.2.21).

Rebuilding the poller cache (tested web and cli) does not help.

Cacti is running on Debian 11, php 7.4
