I am trying to use Parse JSON to format contents of a variable. It will not let me click on the schema section and start typing. I tried making a test flow and that works; however, even when I copy the working Parse JSON action into this flow it removed the schema section and will not allow me to insert the test. I also made a copy of the flow that I want to run and then added a Parse JSON action there, but again, it removes the schema section. It will not even allow me to "Generate from Sample."
