undefined method `probing_facet' for...

Foreman 1.22, your plugin from that repo. The error Oops, we're sorry but something went wrong undefined method `probing_facet' for # is triggered when trying to access the host details page (fundamentally breaking all Foreman host page functions.

In looking through the code, there are a number of cases where probing_facet and probing_facets are used. Perhaps the problem is somewhere in there?

Also, are you still maintaining this plugin? You have a number of your own pull requests and issues open from 2018; it's looking like this may no longer be maintained...
