I am trying to add a flow Group under a Node and I am getting the error stated in the question. Can anyone provide some insight into what keys the API is complaining about. Here is the code snippet that reports the error. It is in YangDataUtils.java

public static Map<qname,object> getKeyMap(CompositeNode node, List<qname> keys) { Map<qname,object> map = new HashMap<>(); for(QName key : keys) { SimpleNode keyNode = node.getFirstSimpleByName(QName.create(node.getNodeType(), key.getLocalName())); checkArgument(keyNode != null,"Node must contains all keys."); Object value = keyNode.getValue(); map.put(key, value);</qname,object></qname></qname,object>

    }
    return map;
}

The node type is "bucket"

Here is the callstack:
