Quick newbie question:
According to docs, settings are global for the trigger, and handler settings are per instance.
I tried the REST trigger using the Web UI and I was prompted for a port number in both flows. I tried entering both values, and it looks like the compiled app was starting 2 separate servers that wanted to bind to the same address.
Ok, I just figured it out.
I shouldn't be pressing on "New action" at the top. I need to hover over the existing flow and another "New action" button appears that re-uses the same instance of the REST trigger.
