如何访问Dialogflow回退意图中的先前对话详细信息

Question

What would be the best way of accessing the previous conversation details when Dialogflow maps the input to a fallback intent?

We'd like to steer the user back into the right direction by re-prompting the last suggestion chips that were given.

The way we do it now is by manually saving the last suggestions and manually resetting them if the conversation is progressing to new intent. Not optimal and error prone.

It would be good if all fallback intents contained the "last intent/response" information.

I also can't find the isFallback properety on the DialogflowConversation object in the AoG SDK. So we're not able to reliably implement logic in the middleware handler. The isFallback property would be very useful to have access to on the conversation object in intent handler functions.

Any best practices for reliably setting and resetting a memory of last conversation for usage in case of fallback?

Answer 1

You can save all your current intent response details in a new output context. Fetch that previous intent response from the previous intent output context and the use that data to create a new response for the fallback intent.

Answer 2

how about if you use conv.action or conv.intent to check for your fallback intent? You can create a middleware function that stores all the information you need from each conversation in user.data if it is not a fallback intent and use that in your fallback intent handler.
