  1. Thank you! I have a question though, when I implemented it this way, some of the chunks went missing. The res.on(‘data’) part wasn’t getting called. I did manage to fix it with doing the appendFileSync() inside of a ‘for await(const chunk of req)’ , but I’m not sure what the problem was. I was wondering if you had any clues..
