Returns wrong datatype inside array, e.g.

Test Client> getMetaData Vehicle.OBD.DTCList 
{
    "action": "getMetaData", 
    "metadata": {
        "Vehicle": {
            "children": {
                "OBD": {
                    "children": {
                        "DTCList": {
                            "datatype": "string[]",

Fine

Test Client> setValue Vehicle.OBD.DTCList  ["2","2"]
{
    "action": "set", 
    "requestId": "e7bbd345-4957-40d9-acdd-a55bafd65a0c", 
    "ts": "2022-03-24T17:24:42.1648139082Z"
}

Test Client> getValue Vehicle.OBD.DTCList 
{
    "action": "get", 
    "data": {
        "dp": {
            "ts": "2022-03-24T17:24:42.1648139082Z", 
            "value": ["2", "2"]
        }, 
        "path": "Vehicle.OBD.DTCList"
    }, 
    "requestId": "934fc377-fe78-4dbe-8f04-e5675ef19b7b", 
    "ts": "2022-03-24T17:24:53.1648139093Z"
}

Not good

Test Client> setValue Vehicle.OBD.DTCList  [2,2]
{
    "action": "set", 
    "requestId": "3df5346a-40c9-4bf9-817b-df014e44a1e6", 
    "ts": "2022-03-24T17:25:20.1648139120Z"
}

Test Client> getValue Vehicle.OBD.DTCList 
{
    "action": "get", 
    "data": {
        "dp": {
            "ts": "2022-03-24T17:25:20.1648139120Z", 
            "value": [2, 2]
        }, 
        "path": "Vehicle.OBD.DTCList"
    }, 
    "requestId": "32702e2c-f4df-46ca-a7d3-b6346bedcac0", 
    "ts": "2022-03-24T17:25:21.1648139121Z"
}

Test Client> 

Expectation: Should be string array, because it is a String list AND VISS wants everything as string. Maybe the client should give everything as string (because I think that is how wie "fixed" it for scalar types)

Good example

Test Client> setValue Vehicle.Speed 200
{
    "action": "set", 
    "requestId": "23791ba4-91f8-4cac-b48d-7a59d64a6ab3", 
    "ts": "2022-03-24T17:27:53.1648139273Z"
}

Test Client> getValue Vehicle.Speed 
{
    "action": "get", 
    "data": {
        "dp": {
            "ts": "2022-03-24T17:27:53.1648139273Z", 
            "value": "200"
        }, 
        "path": "Vehicle.Speed"
    }, 
    "requestId": "756b4caa-d7fa-45d1-9059-70b9a17ba0e0", 
    "ts": "2022-03-24T17:28:00.1648139280Z"
}
