What are some common mistakes when using async middleware?

Some common mistakes include not handling errors properly, forgetting to await async functions, and not returning the next middleware.

Can you explain why not awaiting async functions is a problem?

Not awaiting async functions can lead to unexpected behavior, as the middleware may finish executing before the async operation completes.

What should I do to handle errors in async middleware?

You should use try-catch blocks to catch errors and pass them to the next middleware using next(err).

Are there any best practices for writing async middleware?

Yes, always return promises, handle errors gracefully, and ensure that you call next() appropriately to avoid hanging requests.
