Issue Description:

While adding a new sNSSAI node to the sNSSAIList under NearRTRIC, the update is happening partially. Refer the attachment (Put Data.txt) for the steps for reproducing the issue.

Note 1. The .yang files in the original attachments contain windows CR/LF lien endings which result in an error when creating a schema set. Attached now is yang-files.zip which has the correctly formatted files

Note 2. When creating the data node for the first time a 'POST' operation should be used instead of 'PUT' as shown in the above .txt file

API used:

curl -g -H "Authorization: Basic Y3BzdXNlcjpjcHNyMGNrcyE=" -H "Content-Type: application/json" --request POST 'http://localhost:8883/cps/api/v1/dataspaces/E2EDemo/anchors/ran-network-anchor/list-node?xpath=/ran-network/NearRTRIC[@idNearRTRIC=%2711%27]/attributes/pLMNInfoList[@mcc=%27310%27%20and%20@mnc=%27410%27]' --data-raw '{
"sNSSAIList":[
{
"sNssai":"1000-1000",
"status":"ACTIVE",
"configData": [ { "configParameter":"dLThptPerSlice", "configValue":30 }, { "configParameter":"uLThptPerSlice", "configValue":30 }, { "configParameter":"maxNumberOfConns", "configValue":200 }
]
}
]
}'

Highlighted fragment (configData) which is an nested element under sNSSAIList is not added after the API execution.
