Error not reported when path and payload keys are inconsistent

Adding a single service function with inconsistency between path and JSON name

put /config/service-function:service-functions/service-function/fw-zz/

{
"service-function": [

{ "ip-mgmt-address": "20.0.0.11", "type": "firewall", "name": "fw-yy" }

]
}

This is the actual Service Function created

{
"service-functions": {
"service-function": [

{ "ip-mgmt-address": "20.0.0.11", "name": "fw-yy", "type": "firewall" }

}
}
}

Some things to notice:
The service function name from the path "fw-zz" was ignored. The actually created service function name was "fw-yy"
There was no callback. OndataChanged() was never called.
