This is a configuration release.
Options have been added to netbox_setup_objects.yml-sample for create_vms_templates and create_lxc_templates -- where the default values are False.
This behavior was added so that you can optionally add vms and/or lxc templates should you be using them in your Proxmox environment(s). Some customers reported that they are not using vms and/or lxc templates, so when creating custom fields they got errors about missing templates. These configuration changes should resolve those issues.
