Answer 1

This way it works for me.

const dialogflow = require('dialogflow');
var projectId = ""; // your dialogflow project id when you click on settings of the DF agent
var sessionId = ""; // session ID
var config = {
// use credentials or keyFilename i'm using keyFile
    // credentials: {
        // private_key: privateKey,
        // client_email: clientEmail,
    // }
        keyFilename: './google.json'
};

var sessionClient = new dialogflow.SessionsClient(config);

async sendTextMessageToDialogFlow(textMessage) {
        // Define session path
        const sessionPath = sessionClient.sessionPath(projectId, sessionId);
        // The text query request.
        const request = {
            session: sessionPath,
            queryInput: {
                text: {
                    text: textMessage,
                    languageCode: 'en'
                }
            }
        }
        try {
            let [responses] = await sessionClient.detectIntent(request)
            console.log(responses);
        } catch (err) {
            console.error('DialogFlow.sendTextMessageToDialogFlow ERROR:', err);
            throw err
        }
    };
