The first time I try to delete a host provisioned using a new 1.15.0 smart-proxy I get an error and get kicked back to the main host list. If I try to delete it a second time however it works with no issues. I installed the smart-proxy via yum and both the foreman and foreman-proxy are running on CentOS 7. I've attached the full stack trace from the error.

An issue that may be related, I receive a report or two from the proxy with the following:

warning     Puppet     Unable to fetch my node definition, but the agent run will continue:

warning     Puppet     Could not find terminus rest for indirection node

err     /File[/var/lib/puppet/lib]     Failed to generate additional resources using 'eval_generate': Could not find terminus file for indirection file_metadata

err     /File[/var/lib/puppet/lib]     Could not evaluate: Could not retrieve file metadata for puppet://syseng-foreman.dallas.zixnet.com/plugins: Could not find terminus rest for indirection file_metadata

Wrapped exception:

Could not find terminus rest for indirection file_metadata

err     Puppet     Failed to apply catalog: Could not find terminus rest for indirection catalog

After running puppet agent -t on the proxy host it clears up for a cycle or two.
