[NETCONF-1174] Leaf-list creation fails on min-element violation

Thu, 5 Oct 2023 10:22:51 +0000

Leaf-list resource creation fails due to min-element condition violation, even when the number of leaf-list elements is correct.

Steps to reproduce:
1) Add "test-container-childs" model to netconf-testtool

module test-container-childs {
    namespace "http://example.com/test/container/child";
    prefix "tcc";
    revision 2023-09-28;
    
    container root-leaf-list-container {
        container nested-leaf-list-container {
            leaf-list leaf-list-with-min-elements {
                min-elements 1;
                max-elements 3;
                type string;
            }
        }    
    }
}

2) Send a request to populate "leaf-list-with-min-elements"

POST URI: 
rests/data/network-topology:network-topology/topology=topology-netconf/node=36001-sim-device/yang-ext:mount/test-container-childs:root-leaf-list-container/nested-leaf-list-container

Payload:
{
    "leaf-list-with-min-elements": [
      "data1",
      "data2"
    ]
}

3) Response from device:

{
    "errors": {
        "error": [
            {
                "error-tag": "operation-failed",
                "error-info": "TransactionCommitFailedException{message=Netconf transaction commit failed, errorList=[RpcError [message=Netconf transaction commit failed, severity=ERROR, errorType=APPLICATION, tag=operation-failed, applicationTag=null, info=null, cause=NetconfDocumentedException{error-type=APPLICATION, error-tag=operation-failed, error-severity=ERROR, error-info={}, message=RPC during tx failed.

                "error-message": "Transaction(POST) not committed correctly",
                "error-type": "application"
            }
        ]
    }
}
