Primary IP assignee ID is null in API response but 0 in JSON output

[jooola]

TL;DR

The API Response and JSON output diverge in how they represent the assignee_id field.

Expected behavior

The assignee_id should be null in the json output if the API response is null.

Observed behavior

The assignee_id is 0 in the JSON output when the API response is null

Minimal working example

export HCLOUD_TOKEN="$(get-tmp-hcloud-token)"
hcloud primary-ip create --type ipv4 --name tmp --datacenter fsn1-dc14
HCLOUD_DEBUG=true hcloud primary-ip describe tmp --output json
