1. Don't call setEncoding() method, because by default, no encoding is assigned and stream data will be returned as Buffer objects
2. Call Buffer.from() in on.data callback method to convert the chunk value to a Buffer object.

http.get('my_url', (response) => {
  const chunks = [];
  response.on('data', chunk => chunks.push(Buffer.from(chunk))) // Converte `chunk` to a `Buffer` object.
    .on('end', () => {
      const buffer = Buffer.concat(chunks);
      console.log(buffer.toString('base64'));
    });
});
