I'm making a bot for discord, and I have problems with mongose when uploading the app to heroku, it works fine locally but it crashes on heroku with the following error:
2022-02-11T00:00:17.341218+00:00 app[worker.1]: QueryCursor.prototype.map = function(fn) {

As I said it works fine locally but not on heroku and I don't know why it happens, can someone help me?
