When posting reports from puppetserver 8 to Foreman 3.12, I believe. some error checking should be done in https://github.com/theforeman/puppet-puppetserver_foreman/blame/ad11b503311c8bc51f7447898f740b862838ab70/files/report.rb#L69 I dunno, but anything in the 200, 201 range should be considered acceptable. I had a situation where Puppetserver was being rejected by Foreman with a 403 Forbidden error, but that got swallowed by the report processor. Thoughts?
