I am using module-alias within my nodejs application.
Locally everything works fine, the file path and modules are being found.

However, when deploying on Heroku none of my aliases are being recognized and this error occurs


Error: Cannot find module 'app/models/socket.js'

const SocketModel = require('@models/socket.js');

const app = require('@root/app.js');

You need to remove the slashes at the end of the paths under "_moduleAliases" like so:

"_moduleAliases": {

 "@root": ".",

 "@db": "db",

 "@models": "models",

 "@util": "util",

 "db": "db/db.js",

 "config.js": "config.js"

}
