and this is my code:
const mongoose = require('mongoose');
const connectDB = async () => {
const conn = await mongoose.connect(process.env.MONGO_URI,
{
useNewUrlParser: true,
useCreateIndex: true,
useFindAndModify: false,
useUnifiedTopology: true
});
console.log(`MongoDB Connected: ${conn.connection.host}`);
};
module.exports = connectDB;

Seems to be the same as: MongoParseError: options useCreateIndex, useFindAndModify are not supported
From the Mongoose 6.0 docs:
useNewUrlParser, useUnifiedTopology, useFindAndModify, and useCreateIndex >>are no longer supported options. Mongoose 6 always behaves as if >>useNewUrlParser, useUnifiedTopology, and useCreateIndex are true, and >>useFindAndModify is false. Please remove these options from your code.
