[NETCONF-847] Rfc 8040 - 500 response when reading data from empty device with xml

Thu, 20 Jan 2022 16:42:13 +0000

During read from device when the config datastore is empty, with the following url and xml headers:

http://localhost:8181/rests/data/network-topology:network-topology/topology=topology-netconf/node=test/yang-ext:mount?content=config

instead of empty response we get a response with status code 500 and following exception in the log:

12:24:41.080 WARN [qtp343659091-427] unhandled due to prior sendError
