Upload Error

I'm facing an upload error, it says 500 internal error in my terminal and whenever I give devvit upload in my terminal, it shows "Uploading new version "0.0.1" to Reddit... Error" and a long html/css/js code is coming on my terminal. When I asked what that long code was about, it said "It is some internal server error" am I only one facing this now? If no, can someone help me fix it?
