Reminder Schedule in Form

I want to use the reminder schedule in a form to remind the user if he hasn’t answered the question for the next slot yet. But when I return the ReminderSchedule in the action ask_for_slot, the bot automatically fill the requested slot with the string “[‘EXTERNAL’: EXTERNAL_reminder]” and the reminder message does not show up. Instead, the form receives the wrong format for the slot and asks the user again for the slot.

Please help me. Thanks
