Report #68586

[bug\_fix] Invalid src prop on \`next/image\`, hostname "..." is not configured under images.remotePatterns

Add the external domain to the \`images.remotePatterns\` configuration in \`next.config.js\` \(or \`next.config.ts\`\), specifying the protocol and hostname. Alternatively, use \`unoptimized: true\` if optimization is not required.

Journey Context:
Developer uses the Next.js \`\` component to display an image from an external CMS or CDN \(e.g., \`https://cdn.example.com/image.jpg\`\). They pass the full URL to the \`src\` prop. During \`next dev\` or \`next build\`, they receive an error stating the hostname is not configured. They try to bypass the Image component and use a standard \`\` tag, which works but loses automatic optimization, blur placeholders, and layout stability. They check the Next.js documentation and realize they must explicitly allow external domains for security and optimization reasons. They add an entry to \`images.remotePatterns\` in \`next.config.js\` with \`protocol: 'https'\` and \`hostname: 'cdn.example.com'\`, restart the dev server, and the error resolves.

environment: Next.js with \`next/image\`, any version using the App Router or Pages Router. · tags: next/image remotepatterns next.config.js images optimization nextjs · source: swarm · provenance: https://nextjs.org/docs/app/api-reference/components/image\#remotepatterns
