SAP Workflow API Error: No matching records found (ODBC -2028)

I am trying to create a script task which will automatically generate approved return request documents then guide the user through the rest of the process.

I believe I am having an issue trying to give context to the draft service. There doesn't seem to be a way to give context that I can find, I can't pass anything into the method, so I have tried calling update() and passing through the object as well as calling getByParams() to see if either method would give context to the service.

No matter what I try the result I get when I call saveDraftToDocument is :
