MongooseError: Mongoose.prototype.connect() no longer accepts a callback at Mongoose.connect

Question

throw new MongooseError('Mongoose.prototype.connect() no longer accepts a callback');
^

The dependencies in the project are:
"dependencies": {
"express": "^4.18.2",
"mongoose": "^7.0.3"
},
"devDependencies": {
"nodemon": "^2.0.22"
}

Following is the code snippet in 'db.js':
const mongoose = require("mongoose");

const mongoURI = "mongodb://localhost:27017/";

const connectToMongo = () => {
mongoose.connect(mongoURI, () => {
console.log("Connected to Mongo Successfully!");
});
};

module.exports = connectToMongo;

Also, the code snippet from 'index.js':
const connectToMongo = require("./db");

connectToMongo();

This solution worked for me: https://stackoverflow.com/questions/75774347/throw-new-mongooseerrormongoose-prototype-connect-no-longer-accepts-a-callba

These are the changes need to be made in 'db.js':
const mongoose = require("mongoose");
const mongoURI = "mongodb://localhost:27017/";

const connectToMongo = async () => {
try {
mongoose.set("strictQuery", false);
mongoose.connect(mongoURI);
console.log("Connected to Mongo Successfully!");
} catch (error) {
console.log(error);
}
};
module.exports = connectToMongo;

-----------------------------------------

TERMINAL MESSAGE:
[nodemon] restarting due to changes...
[nodemon] starting `node .index.js index.js`
Connected to Mongo Successfully!

The Error will be resolved after changing your code with this:

const mongoose = require("mongoose");
const <your given name> = "mongodb://localhost:27017/";

const <your given name> = async () => {
try {
mongoose.set("strictQuery", false);
mongoose.connect(<your given name>);
console.log("Connected to MongoDB Successfully!");
} catch (error) {
console.log(error);
}
};
module.exports = <your given name>;
