I'm facing a challenge with receiving responses from dialogflow, even though other express calls are functioning properly.
I believe the issue lies within the agents, but I am unsure of the specific problem or how to resolve it. That's why I have turned to this platform for assistance.
Important points to keep in mind:
- This code is being integrated into an existing, tested express application
- Testing has been conducted using Postman
- The Dialogflow fulfillment template webhook can be accessed here
- The console successfully outputs
We got hours!, but then stops - If you comment out lines
57 through 62 (the if section)and uncomment line56, the code responds as expected - The issue is likely within the
agents.hoursfunction - I have also attempted to use
this.currentlyOpen() === true
Many thanks in advance.
