I'm connecting to a .Net framework via OData 4.0 connector.The connection has been created and sync'd successfully showing all fields that are in the metadata. However when I navigate to the external object or try to SOQL query it I get 
External Object Error
Could not deserialize feed: 

It seems salesforce is expecting the data in a way that the oData connector is not sending. I have access to the oData connector. How should the data be getting sent?
What is the best way to troublshoot this?
