When creating a flow, this error arises.

    As @ajpayne indicated, you likely have some sort of mismatched variable type and/or missing data being passed between PVA and Power Automate.

     

    Power Automate can only accept, and can only return, text, number, and yes/no (boolean). If you update inputs/outputs in Power Automate after you've already added the flow in PVA that can also create problems as well. You can click on the "..." in the top -right corner of the Power Automate node within PVA and select "Refresh" to refresh the connection to the flow and ensure PVA understands what it needs to send to, and what it gets from, Power Automate (see below screenshot)

    I was getting that error when my variable type saved by pva didn't match the variable type being sent back to power automate. So if I have a "choice" variable and power automate is expecting a string variable, it will give you that error.
