I have multiple required slots, and Alexa asks me for them just fine, thanks to Dialog.Delegate .
But at the end, when I answer with the last required slot, nothing happens, because the dialogState is still "IN_PROGRESS", not in "COMPLETED". It should be since all the required slots are filled (I see them in the Intent request). Moreover Alexa doesn't ask me for anything.
Do you have any idea what is going wrong ?
