Microsoft Planner Task to Service Desk Plus Request - error n4001

Microsoft Planner Task to Service Desk Plus Request - error n4001

Hi there.

I'm trying to create a flow that will create a new request in ServiceDesk Plus when a new task is created in Microsoft Planner. I have succesfully connected both Planner and ServiceDesk Plus, and have configured the 'create request' section but on testing, the flow generates the following error. I'm confused as there is nowhere for me to specify an 'id':
"ServiceDesk Plus Cloud says "Error Code :\n4001, Error\nMessage :Unable to parse the given data for id ,\nField :id , Type :failed""
