"message": Target class controller [App\\Http\\Controllers\\UploadController] does not exist.",

It appears Laravel is failing to find your Controller. Try clearing complied files and let composer try to auto-discover relevant classes.

In your terminal run these two commands one after the other.

php artisan clear-compiled 

composer dump-autoload
