I am creating a chat bot in DialogFlow CX that is calling a node.js function in Google Cloud Functions that makes an external API Call. As an aside I am new to all three of these but feel like I am pretty close. The problem I am running into is my google cloud function is finishing and sending a response back to DialogFlow Cx prior to my external api call finishing up. I know my external API call is working and finishing because in logs I see that after the main google cloud function completes that the results of the API call are logged, I just need it to finish before the main google cloud function can finish. Any help is appreciated. Below is the code and log messages.

Code

const functions = require('@google-cloud/functions-framework');
const https = require('https');

let orderStatus = "Unknown";

//helloHttp is entry point for google cloud 
exports.helloHttp =(req, res) => {
  
  const orderNumber = req.body.sessionInfo.parameters.ordernumber;
  console.log(orderNumber);
  
  orderStatus = getOrderStatus(orderNumber, orderStatus);
  

  const jsonResponse = {
    fulfillment_response: {
      messages: [
        {
          text: {
            text: [orderStatus],
          },
        },
      ],
    },
  };
  res.status(200).send(jsonResponse); 
  console.log(orderStatus)
};

function getOrderStatus(orderNumber, orderStatus){

  var options = {
    'secret stuff'
  };

  var req = https.request(options, (res) => {
    console.log('statusCode:', res.statusCode);

    let rawData = ''
    res.on('data', chunk => {
      rawData += chunk
    })

    res.on('end', () => {
      const parsedData = JSON.parse(rawData)
      console.log(parsedData);
      orderStatus = parsedData.order.status;
      console.log(orderStatus);
    })
  });

  req.on('error', (e) => {
    console.error(e);
  });
  
  req.end();

  return orderStatus

};

Thought maybe this is an async problem but not really sure how to address
