Connector execution failed

Hi, I have created my own Assisted REST Connector. When I try to execute it I get the following erros message: "Unable to process the case:Connector execution failed. Http status code -200, The -globals- parameter must be a valid JSON". What does this mean? Where do I define the global parameter? From what I can understand from the user's guide, global parameter is only used in custom connectors. The API that I try to invoke returns json, and looks like this: {"Kundeid":1,"KundeNummer":"11","KundeNavn":"Test","Etternavn":"TestEtternavn"} The output configuration is attached. Thanks
