Plugins » Discovery

On a freshly installed system (Foreman 1.13.2, Discovery Plugin 7.0.0) on a new discovered host I select the action "Provision" and then in the Wizard no Hostgroup only "Create Host". On the "Operating System" tab if I select the Architecture but Operating system is not selectable (still dark gray). Provisioning using PXE and Compute Resource works fine, so I think the problem is somewhere in the Discovery plugins GUI.

I had a look into Browsers Developer Tools and can see a POST-Request with Data.

discovered_host[architecture_id]: "1" 

The answer (500) shown there is:
