Help creating a cable for Netbox 4.2.5

[atxmstr]

Hi, I have this script to test the creation of a cable using pynetbox (7.4.1) on Netbox 4.2.5:

import paramiko
import pynetbox

NETBOX_URL = "xxxxxxxxxxxxxx"
NETBOX_API_TOKEN = "xxxxxxxxxx"
local_host = "SW1"  # Hardcoded local device name
remote_host = "SW2" # Hardcoded remote device name

nb = pynetbox.api(NETBOX_URL, token=NETBOX_API_TOKEN)

# Prepare cable data
cable_data = {
    "side_a_device": local_host,             # Local device name
    "side_a_type": "dcim.interface",         # Termination type for side A
    "side_a_name": "ethernet1/1/50",         # Local termination name (interface name)
    "side_b_device": remote_host,               # Remote device name
    "side_b_type": "dcim.interface",         # Termination type for side B
    "side_b_name": "ethernet1/1/50",         # Remote termination name (interface name)
    "type": "mmf-om4",                       # Cable type (as required)
    "color": "00ffff",                       # Cable color (as required)
    "status": "connected",                   # Cable status
}

# Log the cable data before creation
print(f"Prepared cable data: {cable_data}")

# Attempt to create the cable
try:
    nb.dcim.cables.create(cable_data)
    print(f"Cable created: {cable_data['side_a_name']} <-> {cable_data['side_b_device']}:{cable_data['side_b_name']}")
except pynetbox.RequestError as e:
    print(f"Failed to create cable: {e.error}")

But when I run it, got this error:

 Prepared cable data: {'side_a_device': 'SW1', 'side_a_type': 'dcim.interface', 'side_a_name': 'ethernet1/1/50', 'side_b_device': 'SW2', 'side_b_type': 'dcim.interface', 'side_b_name': 'ethernet1/1/50', 'type': 'mmf-om4', 'color': '00ffff', 'status': 'connected'}
Failed to create cable: {"__all__":["Must define A and B terminations when creating a new cable."]}

If I feed the contents of cable_data into Cable Bulk Import --> Direct Import the cable is successfully created.

Can anyone point me to what am I doing wrong?

TIA
