YANG PUT - Change Key Value

[neteng1]

This is related to YANG module Cisco-IOS-XE-wireless-wlan-cfg.

The container I'm working on is below. Is it possible to change the value of "policy-profile-name" after the resource is created? When I attempt to do so, I receive a 'mismatched keypath' error. 

container wlan-policies {
      description
        "WLAN policy configuration";
      list wlan-policy {
        key "policy-profile-name";
        description
          "List of WLAN policy configurations";
        uses wireless-wlan-cfg:st-wlan-policies;
      }
    }

{
    "errors": {
        "error": [
            {
                "error-message": "mismatched keypaths: /wireless-wlan-cfg:wlan-cfg-data/wireless-wlan-cfg:wlan-policies/wireless-wlan-cfg:wlan-policy[wireless-wlan-cfg:policy-profile-name='POLICY_PROFILE_1_NEW'] , /wireless-wlan-cfg:wlan-cfg-data/wireless-wlan-cfg:wlan-policies/wireless-wlan-cfg:wlan-policy[wireless-wlan-cfg:policy-profile-name='POLICY_PROFILE_1']",
                "error-path": "/Cisco-IOS-XE-wireless-wlan-cfg:wlan-cfg-data/wlan-policies/wlan-policy=POLICY_PROFILE_1",
                "error-tag": "malformed-message",
                "error-type": "application"
            }
        ]
    }
}

Hello wizi

You cannot change key of the list element. Basically you need delete the existing element and then create element with new key.
