Buggy POST /v2/inventory/stocktaking/productline/list

While implementing stock-taking using the API we encountered a bug in the API.

Field count and location.id has no effect when issuing POST /v2/inventory/stocktaking/productline/list

POST /v2/inventory/stocktaking/productline/list
[
    {
        "stocktaking": {
            "id": 1040
        },
        "product": {
            "id": 21494313
        },
        "location": {
            "id": 13
        },
        "count": 5
    }
]

response payload:

{
    "fullResultSize": 0,
    "from": 0,
    "count": 1,
    "versionDigest": null,
    "values": [
        {
            "id": 1412118,
            "version": 0,
            "url": "api.tripletex.io/v2/inventory/stocktaking/productline/1412118",
            "stocktaking": {
                "id": 1040,
                "url": "api.tripletex.io/v2/inventory/stocktaking/1040"
            },
            "product": {
                "id": 21494313,
                "url": "api.tripletex.io/v2/product/21494313"
            },
            "count": 0,
            "unitCostCurrency": 0,
            "costCurrency": 0.00,
            "comment": "",
            "counted": false,
            "counter": null,
            "dateCounted": null,
            "expectedStock": 0,
            "location": null
        }
    ]
}

as count is 0 and location is null in the response.

One could work around this in a less performant way by issuing a single POST for each line to add:

POST /v2/inventory/stocktaking/productline
{
    "stocktaking": {
        "id": 1040
    },
    "product": {
        "id": 21494313
    },
    "location": {
        "id": 13
    },
    "count": 5
}

response payload:

{
    "value": {
        "url": "api.tripletex.io/v2/inventory/stocktaking/productline/0"
    }
}

in this request, the field count is working, but location.id does not. Since response payload nor headers do not contain the ID of the line added, one could not go further by issuing PUT /v2/inventory/stocktaking/productline/{ID}/:changeLocation?warehouseLocationId=39 to update the location on the line.

Start by reproducing POST /v2/inventory/stocktaking/productline/list with the payload shown, then compare it with POST /v2/inventory/stocktaking/productline. Trace the handling of count and location.id for both endpoints, including the subsequent :changeLocation operation. Done means the list endpoint persists both fields and the single-line endpoint returns enough information to update the location.
