[NETCONF-1178] POST request with insert parameter fails if target URI points the list

Relates — Fri, 24 Nov 2023 09:06:42 +0000

POST requests inherently operate on parent resources in the path. This makes it impossible to utilize the `insert` query parameter in the desired manner.
When the parent resource root (which is a container) is used, the application assigns the insert parameter to the container, rather than to the child list items which we intend to update.
Example

curl --location --request POST 'http://localhost:8181/rests/data/network-topology:network-topology/topology=topology-netconf/node=17830-sim-device/yang-ext:mount/user-ordered-list:root?insert=last' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic YWRtaW46YWRtaW4=' \
--header 'Cookie: JSESSIONID=node01orql8nxe3xvz18848b91d7c1z1.node0' \
--data-raw '{
  "user-ordered-list:items": [
    {
      "id": 1,
      "name": "name"
    }
  ]
}'

Error Received:

{
    "errors": {
        "error": [
            {
                "error-tag": "bad-element",
                "error-message": "Insert parameter can be used only with list or leaf-list",
                "error-type": "protocol"
            }
        ]
    }
}

A similar situation arises when using a list as the parent resource. In this case, the application assigns the insert parameter to the parent list and demands an ordered-by-user statement.
