Reminder not cancelling


I’m trying to cancel a reminder I created, but I can’t.

With reference to this guide, I first created the reminder, like that:

ReminderScheduled("utter_treatment_finished", new_dt_end, kill_on_user_message=False, name="treatment_finished")

And then tried to cancel it like that:


and also tried only with the name:


In both cases, my reminder is still displaying as if the ReminderCancelled was not there.

@akelad, @Ghostvv I saw you handled this type of issue before… can you help me?

If I try to cancel all reminders with ReminderCancelled() (according to what it says in the guide), I get this error:

 Exception occurred while handling uri: 'http://action_server:5055/webhook'

Ok I found a workaround: ReminderCancelled("utter_treatment_finished", name="treatment_finished") seems to work.

I don’t understand why I need to specify an action name though… isn’t the name of the reminder I want to cancel enough?

Which Rasa Open Source and Rasa SDK versions are you using ? We recommend to trigger & cancel reminders with intents since version 1.7 (we also updated the docs) Events

Hi, I’m actually using version 1.7
