Getting a similar issue when using the nested option for the parent 'parent': {'name': parent, 'virtual_machine': nb_dev.id},

getting the following error:

{'parent': ["Cannot resolve keyword 'virtual_machine' into field. Choices are: _cable_peer, _cable_peer_id, _cable_peer_type, _cable_peer_type_id, _cabled_as_a, _cabled_as_b, _name, _path, _path_id, cable, cable_id, child_interfaces, created, custom_field_data, description, device, device_id, enabled, id, ip_addresses, journal_entries, label, lag, lag_id, last_updated, mac_address, mark_connected, member_interfaces, mgmt_only, mode, mtu, name, parent, parent_id, tagged_items, tagged_vlans, tags, type, untagged_vlan, untagged_vlan_id"]}

Thanks for the report. I've converted this to a discussion and opened a new bug report (#6710) to better capture the potential error conditions. (This will make it easier for people to identify the bug in the future.)
