Pre-conditions:

• no data in /restconf/config/vpp-classifier:vpp-classifier

Steps:
1. GET the cfg data about classify tables: curl -v -su admin:admin http://10.0.0.5:8181/restconf/config/vpp-classifier:vpp-classifier?prettyPrint=true;echo

Result:
Error:
{"errors":{"error":[

{"error-type":"application","error-tag":"data-missing","error-message":"Request could not be completed because the relevant data model content does not exist "}

]}}

Notes:
When I do the same for bridge domains, I get an empty dictionary.

When I do it for interface, I get the same error:
curl -v -su admin:admin http://10.0.0.5:8181/restconf/config/ietf-interfaces:interfaces/interface/local?prettyPrint=true;echo
{"errors":{"error":[

{"error-type":"application","error-tag":"data-missing","error-message":"Request could not be completed because the relevant data model content does not exist "}

]}}
