I am trying to create an appointment through Power Automate using the Dataverse "Get a Row" and "Add a New Row" operations. I will set the "regarding" on the appointment against an account and set "owner" as current user. Both of which are hard coded right now for debugging. The goal is to pass these values from a PowerApp.
This is my current flow.


I am running into this error -
OpenApiOperationParameterTypeConversionFailed. The 'inputs.parameters' of workflow operation 'Add_a_new_row_(legacy)' of type 'OpenApiConnection' is not valid. Error details: Input parameter 'item/_ownerid_value' is required to be of type 'String/uuid'. The runtime value '"Users(d7c6b0dc-9b66-e911-a87c-000d3a30c619)"' to be converted doesn't have the expected format 'String/uuid'.
Seems like it is expecting the GUID in a specific format and I am not passing that to its liking..
Question 1 - Need help in debugging this. Not a lot of help on this topic.
Question 2 - If values are to be passed from PowerApp, should the format be GUID? or TEXT?
