I am trying to scrap a web page and give as response for my chatbot but I am getting empty response from dialogflow but when I log my scrapping object I get them. I am using glitch for my node js server.

How can I resolve this problem.

app.post("/webhook",async function(request,response){
  var intentName = request.body.queryResult.intent.displayName;
  
 
  if(intentName ="give_project"){
    var type_project = request.body.queryResult.parameters['type_project'];
    var project  =  await get_project(type_project);
    //{url:.....,title:arduino,description: this is a arduino project}
    console.log(project);
    try{
    response.json({
      "fulfillmentText":`type project = `
    })
  }
})
async function get_project(type) {
    const browser = await puppeteer.launch({
  args: ['--no-sandbox', '--disable-setuid-sandbox'],
});
    const page = await browser.newPage();
    await page.goto('https://create.arduino.cc/projecthub/search?q=' + type);
    const projects = await page.evaluate(() => {
        let projectsFromWeb = [];
        let elements = document.querySelectorAll('div.mobile-scroll-row-item');
        for (let element of elements) {

            if (element.querySelector('img') != null) {
                projectsFromWeb.push({
                    url: element.querySelector('a.project-link-with-ref').href,
                    title: element.querySelector('span').textContent,
                    description: element.querySelector('p.description').innerText,
                    image: element.querySelector('img').src
                }
                );
            } else {
                projectsFromWeb.push({
                    url: element.querySelector('a.project-link-with-ref').href,
                    title: element.querySelector('span').textContent,
                    description: element.querySelector('p.description').innerText
                });
            }

        }
        return projectsFromWeb;
    });
    await browser.close();

  return projects[getRandomNumber(projects.length)];
}
                                          



function getRandomNumber(max) {
    return Math.floor(Math.random() * max);
  };


// listen for requests
const listener = app.listen(process.env.PORT, () => {
  console.log("Your app is listening on port " + listener.address().port);
});
