non defined attribute in generate_nexus_url function

[akadoya]

Nexus user creation fails because of NoMethodError.
node[:nexus][:ssl][:port] in libraries/chef_nexus.rb is not defined anywhere so I guess it should be node[:nexus][:app_server_proxy][:ssl][:port]

        def generate_nexus_url(node)
          if node[:nexus][:app_server_proxy][:ssl][:enabled]
            "https://localhost:#{node[:nexus][:ssl][:port]}#{node[:nexus][:context_path]}"      <<<<<
          else
            "http://localhost:#{node[:nexus][:port]}#{node[:nexus][:context_path]}"
          end
        end
