Heroku - Memory Leak

Is there a way for me to override the Upload.js service from the plugin? I saw in this issue comment that a workaround for now could be to replace fs.readFile() with fs.createReadStream().

I created the Upload.js file in extensions/upload/services/Upload.js and tried to run it without modifications but even that caused various errors unfortunately.

I really need to find a workaround as soon as possible :slightly_frowning_face:
