Foundation API POST resquest "primary_nic" returns "Unprocessable Entity"

Hi,

I need to use the API to select the primary NIC that Foundation will use to discover nodes. When I try the request :

GET https://[fvm_ip]:8000/foundation/primary_nic

I get the following result :

{
    "primary_nic": 2
}

That is expected. But when I send the same request using POST, which is valid according the documentation, I now get :

{
    "error": {
        "details": [
            "'nic' is a required property"
        ],
        "message": "Unprocessable Entity",
        "session_id": null
    }
}

My understanding is that the request should be used with a parameter or a body specifying the new primary NIC. But The documentation does not state anything about it. So I tried to pass in “nic”:1 as a parameter and as a body, but still the same error.

Is it a bug ? Is the documentation missing some explanations ?
