Understanding the Problem

Common Causes of the Error

Missing Exports: Ensure that your route file correctly exports the router object.

Incorrect Imports: Double-check that you are importing the routes correctly in your main application file.

Middleware Functions: Confirm that any middleware functions used are defined properly.

Step-by-Step Solution

1. Check Your Route File

4. Final Check

After making the above changes, restart your server. If everything is set up correctly – with exports, imports, and routing – your server should start without encountering the middleware error.

Conclusion

If you continue to encounter issues, it's always good to debug by logging the routes and their exports to make sure everything is functioning as expected. Happy coding!
