OK I upgraded to 3.17.2 now I have a new Error:

Instanz allison.dc2.tcsoc.net: undefined method `include?’ for nil:NilClass config_cpu = config.select { |key, _value| config_typed_keys(type)[:cpu].include? key } ^^^^^^^^^

Any help would be appreciated

Hi @kagouros ,

It’s probably worth filing an issue to Issues · theforeman/foreman_fog_proxmox · GitHub

@nadjaheitmann have you seen this issue before with the proxmox plugin?

We currently have some issues with foreman_fog_proxmox and Foreman 3.17+ which all show similar symptoms. We are on it.
