Error exceptions.TypeError 'Interface' object is not iterable when trying to connect interfaces via api.

Environment

  • Python version: 2.7.5
  • NetBox version: 2.4.3

Steps to Reproduce

curl -X POST \
-H "Authorization: Token <TOKEN>" \
-H "Content-Type: application/json" \
-H "Accept: application/json; indent=4" \
https://netbox.fqdn/api/dcim/interface-connections/ \
--data '{ "interface_a": 114022, "interface_b": 114030, "connection_status": true }'

id of interface_a exists:

curl -X GET \
-H "Authorization: Token <TOKEN>" \
https://netbox.fqdn/api/dcim/interfaces/114022/ \
-H "accept: application/json"

{"id":114022,"device":{"id":4177,"url":"https://netbox.fqdn/api/dcim/devices/4177/","name":"API-Test-1","display_name":"API-Test-1"},"name":"1/1","form_factor":{"value":800,"label":"100BASE-TX (10/100ME)"},"enabled":true,"lag":null,"mtu":null,"mac_address":null,"mgmt_only":false,"description":"","is_connected":false,"interface_connection":null,"circuit_termination":null,"mode":null,"untagged_vlan":null,"tagged_vlans":[],"tags":[]}

id of interface_b exists:

curl -X GET \
-H "Authorization: Token <TOKEN>" \
https://netbox.fqdn/api/dcim/interfaces/114030/ \
-H "accept: application/json"

{"id":114030,"device":{"id":4178,"url":"https://netbox.fqdn/api/dcim/devices/4178/","name":"API-Test-2","display_name":"API-Test-2"},"name":"1/1","form_factor":{"value":800,"label":"100BASE-TX (10/100ME)"},"enabled":true,"lag":null,"mtu":null,"mac_address":null,"mgmt_only":false,"description":"","is_connected":false,"interface_connection":null,"circuit_termination":null,"mode":null,"untagged_vlan":null,"tagged_vlans":[],"tags":[]}

Expected Behavior

The interfaces would be connnected.
