Dialogflow CX Intergration with Messenger from Facebook

[riderX]

Hi, I have some issue when I integrate dialogflow cx with messenger. 
The issue is I didn't get response from my bot, I have a suspect that dialogflow failed to send message to user on messenger.
So, my problem now is how to check sending message process in dialogflow to get the detail of error?

Thanks

To see logs for DialogFlow, you would need to enable Cloud Logging in your agent’s general settings. After enabling logging, you’d be able to see DialogFlow logs for requests and responses (including for webhooks). Let me know if you have additional questions.
