             Summary: Handle the default schema correctly when serializing a JSON config
                 Key: MINIFICPP-2290
                 URL: https://issues.apache.org/jira/browse/MINIFICPP-2290
             Project: Apache NiFi MiNiFi C++
          Issue Type: Bug
            Reporter: Ferenc Gerlits
            Assignee: Ferenc Gerlits


The JSON flow configuration comes in two flavors: the default schema and the NiFi schema.  In the default schema, the root node location is {{"."}}, which is a notation borrowed from yaml-cpp to refer to the current node (so {{node["."] == node}}).

This notation is not supported directly by rapidjson; it works when parsing the JSON input because it is implemented in {{flow::Node::operator[]}}.

We need to handle {{node["."]}} when writing the JSON flow configuration, too.
