When refreshing the page, why am I receiving a 404 error for the JS resources on Next.js?

edit

There are several potential causes for receiving a 404 error for JS resources on Next.js when refreshing the page. Here are a few possible reasons:

1. Client-Side Routing: If you're using client-side routing in Next.js (such as with the Link component), then refreshing the page may trigger the browser to request a resource that doesn't exist on the server. This can result in a 404 error for the JavaScript file.

2. Static File Serving: If you're serving your static files (such as JS or CSS) through Next.js, then refreshing the page may trigger the server to look for the file in the wrong location. Make sure you're using the correct path to your static files in your code.

3. Cache Settings: If your server is configured to cache resources for a certain amount of time, then refreshing the page may still show the cached version of the page. This can result in a 404 error for the JavaScript file if it was updated since the cache was created.

To fix the issue, you may need to adjust your code to ensure that the resources are being served correctly, or adjust your server's cache settings to avoid serving outdated resources.
