Foreman » Smart Proxy

Foreman 1.7.1/uppet 3.7.3. Very similar, but not identical to #5856.

Error was:

Warning!
ERF12-2749 [ProxyAPI::ProxyException]: Unable to get environments from Puppet ([RestClient::ResourceNotFound]: 404 Resource Not Found) for proxy https://foreman.my.org:8443/puppet

I initially thought it was b/c of the warnings about directory environments, but those still aren't supported, per #5856 & #6004. puppet.conf attached. My question is: are there puppet module smart class params I should be setting/overriding in the Foreman UI?
