Invoking Yang 1.1 Action on ODL fails for Yang Model containing yang action under augmentation hierarchy.

While Executing yang action requests on ODL via  POST request failes for augmented yang actions see attached screenshot

By going through ODL wiki , it says that QName for augmented yang model would not be supported.

 
 Running into issue  its related to invocation of Yang 1.1 Action on Odl.
 
When I am invoking action on Yang Model having Augmentations like below it fails with Exception : "Augmentation node has no Qname" ** 
 
It occurs at time of getting  :  QName getNodeType() >> path.getNodeType() as shown in below code snippet.
 
In Class : RestconfInvokeOperationsUtil.java     in Restconf Module.
 
private static DOMDataTreeIdentifier prepareDataTreeId(final YangInstanceIdentifier yangIId,
final SchemaPath schemaPath) {
final List<PathArgument> pathArg = new ArrayList<>();
for (PathArgument path : yangIId.getPathArguments()) {
if (path.getNodeType().getLocalName().equals(schemaPath.getLastComponent().getLocalName()))

{ break; }

pathArg.add(path);
}
YangInstanceIdentifier yangInstanceIdentifier = YangInstanceIdentifier.builder().append(pathArg).build();
DOMDataTreeIdentifier domDataTreeIdentifier = new DOMDataTreeIdentifier(LogicalDatastoreType.OPERATIONAL,
yangInstanceIdentifier);
return domDataTreeIdentifier;
}
