414 URI Too Long

What 414 URI Too Long means {#what}

The URI in the request is longer than the server will process. Usually caused by overly long query strings — often from client-side bugs that keep appending parameters in a redirect loop.

When you’ll see a 414 {#when}

• Redirect loops that keep appending to the URL
• Search queries or filter parameters that got out of hand
• Converting a POST-heavy workflow to GET
