• OriginalCNM is the input CNM to the function. We save this during our Translate operation that we do in the beginning of the workflow.
• CNMResponseStream is the name of the stream to write out to- Note this is not an ARN right now.
• WorkflowException is the 'exception' field from the workflow. Probably don't need to change this.
• region is the region of AWS that the ResponseStream resides in.
