Next.js Image Component scenarios to Load Image with Custom Loader in Production Build

next.js image custom-loader JavaScript

I'm confused about I'm experimenting with Hey everyone, I'm running into an issue that's driving me crazy. I'm using the Next.js Image component with a custom loader to dynamically fetch images based on user input, but it works fine in development but fails in production. My loader function looks like this: ```javascript const customLoader = ({ src }) => { return `https://example.com/images/${src}`; }; ``` I use it like this in my component: ```javascript import Image from 'next/image'; const MyImageComponent = ({ imageName }) => { return <Image loader={customLoader} src={imageName} alt="Dynamic Image" width={500} height={300} />; }; ``` In the development environment, everything runs smoothly, and I can see the images being rendered without any issues. However, once I build my application using `next build` and run `next start`, the images unexpected result to load, and I get the following behavior in the console: ``` behavior: Failed to load image from the server. ``` I confirmed that the URLs generated by the loader function are correct, and I can directly access them in my browser. I've also tried clearing the Next.js cache and rebuilding the app, but that didn’t resolve the scenario. Could this be related to how the Image component handles external URLs in production? Any insights or solutions would be greatly appreciated! Is there a better approach? My development environment is Ubuntu. My development environment is Windows 11.
