So when I run my app in deployment, with the backend connecting to MongoDB using MongoClient as follow:
import { MongoClient } from 'mongodb'
const url = process.env.MONGODB_URI
MongoClient.connect(url, { useNewUrlParser: true, useUnifiedTopology: true },(err, db)=>{
console.log(url)
db.close()
})
everything works fine. But if I change it into
import mongoose from 'mongoose'
const url = process.env.MONGODB_URI
mongoose.Promise = global.Promise
mongoose.connect(url, { useNewUrlParser: true, useCreateIndex: true, useUnifiedTopology: true })
mongoose.connection.on('error', () => {
throw new Error(`unable to connect to database: ${url}`)
})
it gives the following error:
webpack://HappyHourWeb/./server/server.js?:29
throw new Error(`unable to connect to database: ${_config_config__WEBPACK_IMPORTED_MODULE_0__["default"].mongoUri}`)
^
Error: unable to connect to database: my_database_url,

My URI is in the form:
mongodb+srv://<username>:<password>@<cluster>.vr5kw.mongodb.net/<dbname>?retryWrites=true&w=majority
Any help is greatly appreciated!
