node.js - Send parameters to webhook on dialogflow sdk v2

Question

I'm trying to send some parameters to dialogflow (api.ai) such as username, email, etc but I couldn't figure it out. The problem is I cannot get/set any specific data (such as username, email, etc.) with Dialogflow v2 Nodejs SDK. I tried to use queryParams.payload (v1: originalRequest) but It didn't work somehow. Also, I tried to trigger custom event with data but I couldn't get any event data on the response. Does someone know how to send some specific data for session talk on dialogFlow?

EXAMPLE OF PAYLOAD

  const projectId = 'test-bot-test-1111';
  const sessionId = user.uuid;
  const languageCode = 'en-GB';

  const sessionClient = new dialogFlow.SessionsClient();
  const sessionPath = sessionClient.sessionPath(projectId, sessionId);

  const request = {
    session: sessionPath,
    queryInput: {
      text: {
        text: query,
        languageCode
      }
    },
    queryParams: {
      payload: {
        data: {
           username: 'bob',
           email: 'bob@test.com'
        }
      }
    }
  };

  let resultReq;

  console.log('request :: ', request, '

');

  try {
    resultReq = await sessionClient.detectIntent(request);
  } catch (err) {
    // eslint-disable-next-line no-console
    return console.error('ERROR:', err);
  }

EXAMPLE OF EVENT

  const projectId = 'test-bot-test-1111';
  const sessionId = user.uuid;
  const languageCode = 'en-GB';

  const sessionClient = new dialogFlow.SessionsClient();
  const sessionPath = sessionClient.sessionPath(projectId, sessionId);

const request = {
    session: sessionPath,
    queryInput: {
      event: {
        name: 'custom_event',
        languageCode,
        parameters: {
          name: 'sam',
          user_name: 'sam',
          a: 'saaaa'
        }
      }
    },
    queryParams: {
      payload: {
        data: user
      }
    }
  };

  let resultReq;

  console.log('request :: ', request, '

');

  try {
    resultReq = await sessionClient.detectIntent(request);
  } catch (err) {
    // eslint-disable-next-line no-console
    return console.error('ERROR:', err);
  }
