"Image Not Found" – Troubleshooting Strapi Images with Next.js

The Scenario: You've got a sleek Next.js frontend and a powerful Strapi backend. You've carefully uploaded your images to Strapi, and you're excited to display them on your website. But when you use the next/image component, you're greeted with the dreaded "Image Not Found" error.

The Code:

import Image from 'next/image';

function MyComponent({ image }) {
  return (
    <div>
      <Image 
        src={image.url} 
        alt={image.alternativeText} 
        width={500} 
        height={300}
      />
    </div>
  );
}

The Problem (Simplified): The next/image component can't find your Strapi images, even though they're stored in Strapi.

Let's Debug:

Here's a breakdown of the common culprits and how to troubleshoot:

1. Incorrect URL:

   • Strapi Image URLs: The url property provided by Strapi might be the wrong format for next/image. Strapi URLs often include a file path relative to the Strapi root, not your frontend's file path.
   • Solution: Use the strapi.config.js file to configure your Strapi public URL. This will ensure correct image URLs are generated:

   module.exports = {
     // ... other settings
     public: {
       url: "http://localhost:1337", // Replace with your actual Strapi URL
     },
   };
   

2. Missing Configuration:

   • CORS: next/image requires images to be served with the correct CORS (Cross-Origin Resource Sharing) headers. If your Strapi server is not properly configured, you'll encounter errors.
   • Solution: Enable CORS in your Strapi project:

   module.exports = {
     // ... other settings
     cors: {
       origin: ["http://localhost:3000"], // Replace with your Next.js frontend URL
     },
   };
   

3. Proxy Issues:

   • Next.js Proxy: If you're using a proxy to access Strapi, the image requests might be blocked due to proxy settings.
   • Solution: Configure your Next.js next.config.js file to enable proxying:

   module.exports = {
     // ... other settings
     async rewrites() {
       return [
         {
           source: '/api/:path*',
           destination: 'http://localhost:1337/:path*', // Replace with your Strapi URL
         },
       ];
     },
   };
   

Additional Tips:

• Inspect Network Requests: Use your browser's developer tools (Network tab) to inspect the image requests. Look for 404 errors or CORS issues.
• Local Development: If you're working on a local development environment, ensure that both Strapi and Next.js are running on different ports, and the ports are correctly specified in your configurations.
• Image Optimization: Utilize the next/image component's built-in features for image optimization (e.g., automatic image format selection, lazy loading).

By carefully checking these points and adjusting your configurations, you'll be able to overcome the "Image Not Found" error and successfully display your beautiful Strapi images within your Next.js application.
