It seems that, under your tratext function(agent), you are translating the "agent" instead of the "agent.text". You could try as following:

As far as I know, responding to a Google Chat (formerly Hangouts Chat) button isn't possible when using the direct Dialogflow integration.

The problem is that the button response can be sent one of two ways:

• An event will be sent back to the bot code indicating the click.
• Using the onClick.openLink.url property, as most of your test show. This will take the person clicking it to the URL in question. But once there, you're taken out of the bot flow.

However, the documentation for the Hangouts Chat integration with Dialogflow doesn't provide any information about how this event is passed to Dialogflow, and the last time I tested it - it isn't.

You can write your own integration using Google Chat's API on something like Cloud Functions or Apps Script and have your script call Dialogflow's Detect Intent API to determine what Intent would be triggered by the user (and determine replies or call the webhook for additional processing). Under this scheme, you can choose how to handle the onClick event. Making your own integration also provides you a way to do Incoming Webhooks, which isn't possible when using the Dialogflow integration.

To access the Facebook User's ID you need to dive in request_.

The issue is that your testIntent() handler function is calling agent.tell(), which isn't a valid method.

I suspect you meant to call agent.add()

You appear to be using multiple objects in a list inside your package.json file, I'm not sure if this is how package.json files are meant to work.

The "error" you're showing is a warning and does not usually prevent things from working. It is saying that it is assuming the environment based on the Project it is running in. If you're accessing a data store in the same project - you shouldn't be encountering any problems with this.

You don't indicate what is happening when you try to call set(), but it sounds like this may not even be happening.

Given the state machine that is depending on the value of the global flag variable, that may not be surprising. Trying to track the conversation this way has two problems:

1. It looks like they're only getting invoked at the welcome Intent. You're not showing this Intent definition, but this may only be happening when the bot is first invoked and not afterwards.

2. Since this is a global variable, and not a value that is attached to the conversation, it could be changed if multiple users tried to use the bot at the same time or if the server it is running on is reset. If you're using Firebase Cloud Functions or the Dialogflow Built In editor, this could happen without you knowing it.

In particular, (2) may be causing it to never get to the state where set() is called.

There does not appear to be anything wrong with the call to set() itself, but you're not doing any error handling. And it looks like you're sending the "You're good to go" message before you know if the set() actually works. To address this, you may want to change addLeads() so it returns a Promise, and then make the call to it also work with a Promise. This might change addLeads() to something like

The Data you pass in chatContext object from Kommunicate chat widget can be access from your fulfillment code. This data is available in request object as part of originalDetectIntentRequest parameter.

This is the example:

The reason behind that is because you defined your function as function visaCountry(agent) { }. Technically trying to access the agent variable from the function scope which you didn't pass and that's why it is undefined.

Just simply pass to visaCountry() to the variable agent.

Like the following:
