Dialogflow x Firebase

[ahuckphin]

I am indulging into dialogflow and firebase however struggling due to a lack of documentation. I am actually not sure if there is a lack of documentation or if I am incapable of finding documentation. For example I am struggling to understand what the following means: 

fuzzylogic.trapezoid
fuzzylogic.reverseGrade
fuzzylogic.triangle
fuzzylogic.grade

So I am looking for documentation for dialogflow in particular for fuzzylogic and firebase integration.

 

Mentioning firebase, I was told by a friend who is also indulging into dialogflow and firebase that when creating a new dialogflow project, it will also automatically create a new firebase project and automatically link the two in the dialogflow fulfilment section. I have yet to experience this.

 

I am actually stuck on marrying dialogflow and firebase. Getting errors like "message": "Webhook call failed. Error: DEADLINE_EXCEEDED. and provided authentication credentials for the app named "[DEFAULT]" are invalid.
