Hey did you happen to figure out your issues with this? It looks like i am running into the same problem.
a friend in need is a friend indeed
Pressing Ctrl + J does not make the debugger appear for me. I also created another button that shows an alert message once pressed, and that looks to be working. It is just the HTTP submit.
To make the debugger appear, you must change settings in Adobe Acrobat Pro.
Open Adobe Acrobat Pro
►Check: Enable interactive console
►Check: Show console on errors and messages
you can also see here how to do it
