Repository API /qrs/servernodeconfiguration/local response way different than docs

[RopoOssi]

I have a very strange problem. We are trying to automate adding virtual proxys to qlik sense using the Repository API. We had a developer working for the company who built the skeleton for the tool but he quit and none of us seem to have any idea how Qlik works. It's a mess and the documentation seems to be something of a mess.

When sending a /qrs/servernodeconfiguration/local GET request I receive a response looking like this:

{
    "id": "",
    "createdDate": "2018-10-22T09:01:18.538Z",
    "modifiedDate": "2018-10-22T09:01:18.538Z",
    "modifiedByUserName": "INTERNAL\\bootstrap",
    "customProperties": [],
    "name": "Central",
    "hostName": "",
    "isCentral": true,
    "nodePurpose": 2,
    "engineEnabled": true,
    "proxyEnabled": true,
    "printingEnabled": true,
    "schedulerEnabled": true,
    "tags": [],
    "temporaryfilepath": "",
    "roles": [
        {
            "id": "",
            "definition": 0,
            "privileges": null
        },
        {
            "id": "",
            "definition": 1,
            "privileges": null
        },
        {
            "id": "",
            "definition": 2,
            "privileges": null
        },
        {
            "id": "",
            "definition": 3,
            "privileges": null
        },
        {
            "id": "",
            "definition": 4,
            "privileges": null
        },
        {
            "id": "",
            "definition": 5,
            "privileges": null
        }
    ],
    "serviceCluster": {
        "id": "",
        "name": "ServiceCluster",
        "privileges": null
    },
    "failoverCandidate": true,
    "privileges": null,
    "schemaPath": "ServerNodeConfiguration"
}

 This looks nothing like what the documentation says it should: 

https://help.qlik.com/en-US/sense-developer/September2019/Subsystems/RepositoryServiceAPI/Content/Se...

The documentation is so bad I have no idea what the configuration looks like and why it should be attached to a key 

loadBalancingServerNodes

 but apparently this is an array. Seriously, what's wrong the that qrs response and why can't people write proper documentation?
