Hey @Shu12388y
Could you please add a README explaining how to run this sample app?
Also, include the test cases generated using Keploy in the sample app

Empty connection string passed to mongoose.connect(). This will cause the database connection to fail. The connection string should be read from environment variables or configuration.

Suggested change

	try {
	await mongoose.connect("");
	const mongoUri = process.env.MONGO_URI;
	if (!mongoUri) {
	throw new Error("MONGO_URI environment variable is not set.");
	}
	try {
	await mongoose.connect(mongoUri);

The DB function immediately disconnects after connecting in the finally block. This defeats the purpose of establishing a connection, as mongoose.disconnect() will close it right away. Remove the finally block or move the disconnect logic to application shutdown.

Suggested change

	} finally {
	mongoose.disconnect();
	}

Corrected spelling of 'DataBase' to 'Database'.

Suggested change

	console.log("DataBase Error" + error);
	console.log("Database Error" + error);

[Copilot]

Error message uses string concatenation which may not display error details properly. Use template literals or proper error formatting: console.error('Database Error:', error);

Suggested change

	console.log("DataBase Error" + error);
	console.log(`DataBase Error:`, error);

[Copilot]

Use console.error() instead of console.log() for error messages to ensure they are logged to stderr and properly categorized.

Suggested change

	console.log("DataBase Error" + error);
	console.error("DataBase Error" + error);

Corrected spelling of 'configration' to 'configuration'.

The MONGO_URI environment variable is defined in docker-compose.yml but not used in the application code (DB.ts has an empty connection string). The application should read this environment variable to establish the database connection.
