Dialogflow CX bot does not display the fulfilment text when called by api

[jocieldoabreu]

Hi guys, I'm struggling with a problem related to calling the Dialogflow API. I'm using an API to call a specific page using the following payload:

{
	session: "projects/xxxx/locations/us-east1/agents/xxxx/session/xxx",
	queryParams: {
	  currentPage: "projects/xxxx/locations/us-east1/agents/xxxx/flows/xxxx/pages/xxxx",
	  parameters: {
		fields: {},
	  },
	},
	queryInput: {
	  text: {
		text: "",
	  },
	  "en",
	},
}

and to call it, I use:

const assistant = new dialogflow.SessionsClient(config);
const [response] = await assistant.detectIntent(request);

I'm trying to call this specific page:

But I don't get any response. No text is sent back.

Now, if I use a parameter, I'll get the response:

But here's the thing, I won't use parameters everywhere. I need to get the fulfillment message.

Does anyone have any idea what I can do? Thank you all!!

I believe you need intents for the flow to  enter the fulfilment page.
