Hi,
I encountered this error (as attached) when checking the "Disable All Tools that Write Output" in the Runtime config. panel.
On top of that I was never able to execute any workflows successfully. The same error I encountered.
Please assist. I have attached my simple workflow with just Input, Select and Output.
More info: The Alteryx version I am using is 2020.1.5.25447 (Alteryx Admin Designer)
