Fix Next.js Error: Invalid src prop in next/image (2025 Guide)

Posted on: April 11, 2025

Encountered an "Error: Invalid src prop in next/image" in Next.js? This error occurs when the `src` prop in the `next/image` component is invalid or improperly configured. Let’s fix it fast in this 2025 guide!

What Causes "Error: Invalid src prop in next/image"?

This error occurs when using the `next/image` component with an incorrect or unsupported `src` value. Common causes include:

• External Domain Not Configured: Using an external URL without adding the domain to `next.config.js`.
• Incorrect Path: The image path is wrong or the file doesn’t exist.
• Missing Width/Height: Not providing `width` and `height` props for non-static imports.

Here’s a Next.js example that triggers the error:

import Image from 'next/image';

export default function Page() {
  return (
    

      {/* This will trigger "Error: Invalid src prop" */}
      
    
  );
}

Running this in Next.js will throw the error if the domain isn’t configured or the URL is invalid.

How to Fix It: 3 Solutions

Let’s resolve this error with practical steps:

(Diagram: Developer uses invalid src, gets error, configures domain, loads successfully.)

Solution 1: Configure External Domains in next.config.js

Add the external domain to `next.config.js` to allow images from that source:

// next.config.js
module.exports = {
  images: {
    domains: ['invalid-url.com'], // Add the domain here
  },
};

// Page component
import Image from 'next/image';

export default function Page() {
  return (
    
  );
}

Adding the domain to `next.config.js` ensures Next.js can load external images.

Solution 2: Use a Local Image or Correct Path

Ensure the image path is correct, or use a local image with static imports:

import Image from 'next/image';
import localImage from '../public/images/my-image.jpg'; // Import local image

export default function Page() {
  return (
    
  );
}

Using a local image or verifying the path prevents `src` errors.

Solution 3: Provide Width and Height Props

Ensure `width` and `height` props are specified for external images:

import Image from 'next/image';

export default function Page() {
  return (
    
  );
}

`width` and `height` are required for external images to prevent layout shifts and errors.

Quick Checklist

• External image? (Add domain to `next.config.js`)
• Correct path? (Verify or use local image)
• Missing dimensions? (Add `width` and `height`)

Conclusion

The "Error: Invalid src prop in next/image" in Next.js can be fixed by configuring domains, verifying paths, and providing dimensions. With these 2025 solutions, your images will load correctly. Got another Next.js error? Let us know in the comments!
