Custome Fields (Object) cannot import into NetBox

[rossnrachel]

In CONNECTIONS->Cables, I want to see the subnet of the Cables two ends, so I create a Custom Fields in CUSTOMIZATION->Custom Fields, named interconnected_subnet,
Object types: DCIM > Cableinterconnected_subnet
Type: Object
Related object type: IPAM > Prefix

Then I add a prefix 192.168.16.20/30 in IPAM->PREFIXES->Prefixes.

But, when I did "Cable Bulk Impoert" in CONNECTIONS->Cables->Import, it pops up an error: "Record 1 cf_interconnected_subnet: Object not found: 192.168.16.20/30"

And my question is how can I import data with custom object fields in NetBox?

Solved. You have to put the numeric ID of the object you're referring to instead of the IP prefix (192.168.20.0/30)
