Looking for a keen eye to see where I have gone wrong.  I  am trying to Post some JSON to the Facebook Marketing API using a custom Zap built in the UI.  When running this through Zapier, I get an error that the JSON node Session cannot be found.  However when I paste this exact JSON into the Facebook Graph Explorer is works perfectly. Attached is the Facebook Graph Explorer Screenshot. 

Here is the Request/Response from Zapier.
