I am trying to validate slots in Form Action, I notice that the validate slots is getting called twice. → first time - from the validate- prefilled slots and again from validate extracted slots. Incase user enters invalid value: If I give a user message-> i.e. bot utterance as a message to the user-> it is shown twice to the user. and then the message to fill the required slot is shown.
Is it possible for the user to correct the input, if the validation fails the first time itself?
