How to restart a dialog directive or empty all slots?

Hello. I am collecting some slots through Alexa in a CollectIntent:

'AMAZON.CollectIntent': function () { 
	if (this.event.request.dialogState !== 'COMPLETED') {
            this.emit(':delegate');
        } else {
	... 
	}
    },

And everything works finde. I can use these slots, do some stuff with them, but when I ask the user if he wants to restart and the/she says yes it doesn't work anymore. I would like to send them back to CollectIntent to restart:

'AMAZON.YesIntent': function () { 
        this.emit('CollectIntent'); 
    },

I would like to know if there is a way to restart a dialog directive (or empty all slots and restart) so that Alexa can collect these slots again? How could I achieve this?

Hi @r-j-b and thanks for your question.

I noticed that you are using version 1 (v1) of the SDK. A new version (v2) was launched back in April and has a number of improvements over v1. There are a few good examples of the implementation of DialogDirective using v2 here and here.

Also, regarding the name of your intent (AMAZON.CollectIntent): this is not a part of the available built-in intents, which use the AMAZON. prefix. In fact, according to the naming conventions, you should not use the AMAZON. prefix when naming your custom intents.

Finally, I noticed that your AMAZON.YesIntent function is sending the user back to CollectIntent. However, you have no function with that name to handle it. Taking the points made in the previous paragraph, you should rename your intent to CollectIntent and that should solve this issue.

Feel free to come back if you have any further questions.

Regards,
Barry
