did you get any solution? I am facing the same issue

hi there, first of all, the code is ok - it was somewhere in the action's configuration - don't know where exactly.
Maybe simply an action can not tolerate changing the configuration while the application is running - what I can advise you is to create a new action and carefully enter the data. Let me know if that helped..
