In Express.js, when you want to specify an HTTP error code using the `Error` object, it's essential to understand how this works. The issue you're facing is likely due to the way Express handles error objects.

🔍 Why This Happens

  • The `res.statusCode` property is used to set the HTTP response status code, but when you create an error object using `new Error()`, it sets the internal error code of Express. This internal error code is usually 500 (Internal Server Error) by default.

🛠️ Step-by-Step Verified Fixes

Method 1: Using the `res.status()` Method

  1. Step 1: Create an error object with a specific status code using `new Error(statusCode)`. For example, `var e = new Error(400);`

Method 2: Using the `res.status()` Method and Setting the Internal Error Code

  1. Step 1: Set the HTTP response status code using `res.status(statusCode)`. For example, `res.status(400);`

✨ Wrapping Up

By following these steps, you should be able to specify the desired HTTP error code using Express.js. Remember to always check the official Express documentation for the most up-to-date information on error handling.
