I'm trying to debug a "handler...was not found in either the main handlers list nor in the listening handlers list" issue.
There are --list-host, --list-tags, and --list-tags options, but nothing for listing registered handlers. I've run ansible-playbook with the "debug" strategy and with -vvvv, but neither of those seem to provide any insight. I don't see any "magic" variables that might contain this information.
Is there any way to show/dump these handlers and/or listeners?
