Currently after multiple data trees are stored in CPS DB. On performing the GET operation on the same data, with xpath set as root "/", the first data tree is returned by the Get Data Node API. This data tree is returned in form of a JSON Object as follows:

{
"multiple-data-tree:last-container": {
"x-leaf": "x-value"
}
} |
Expected Outcome
After the GET API is updated, we want all the data trees to be returned when the xpath is set to root "/" and when a specific xpath is provided we want the functionality to remain as is.
