I believe your go function isn't returning any value.

You're calling request(options).then(...), but what follows from that promise is never returned by go. I recommend you add a return statement:

go = async () => {

  const options = {
    uri: "http://www.somewebsite.com/something",
    transform: function(body) {
      return cheerio.load(body);
    }
  };

  // The only difference is that it says "return" here:
  return request(options)
    .then($ => {
      let scrapeTitleArray = [];
      $(".some-class-in-html").each(function(i, obj) {
        const data = $(this)
          .text()
          .trim();
        scrapeTitleArray.push(data);
      });
      return scrapeTitleArray;
    })
    .catch(err => {
      console.log(err);
    });
};
