An error occurred in executing an Activity Class

Hi all,

Have you ever encountered an error occurred in executing an Activity Class that goes on saying: "each item within the input "Records" must be a record data type. Received: AS Vehicle". It happens since there is a problem with task "Write Vehicle Record" in the process "New Vehicle:"

I am completing Process Modeling 101: Automate Your Business Processes (exercise 10) but used only AX Vehicle (ie Acme exericse app) as a record type in the process model. I mapped the value "=pv!vehicle" for the input of the node and did not use the AS Vehicle (ie Acme Solution app). Any ideas why this happens?

Thank you!
