We are having trouble using the DwNet.Data and SnapObjects.Data and having trouble with Mapping.Method, when using the PowerBuilder RestClient.Submit.  The Mapping.Method is set to 0 and this is causing problems with the processing of the json.  Looks like either DwNet.Data or SnapObject.Data depends on the mapping-method when it deserializes the input json into a datastore/model.

Changing from "mapping-method":0  to "mapping-method":2, then the validation passes and the .NET datastore endpoint works.  Otherwise, the validation fails since the json is incorrectly read and values are mapped to the wrong field.  

Is there a way to change the mapping-method on the PowerBuilder side using RestClient.Submit?  Or is there a standard way to handle this on the .NET side?

Here is the first part of the json with the mapping-method:

{"identity":"removed","version":1,"platform":"PowerBuilder","mapping-method":0,"dataobject":

Here are the options for the mapping-method.  We would like to map to the key of the JSON item:

0 -- Use the index of JSON item to map with the DataWindow column.
1 -- Use the index of meta-columns to map with the DataWindow column.
2 -- Use the key of JSON item to map with the DataWindow column.

Thank you for any help you can provide.
