notFoundComponent: () => {
	return <p>This page doesn't exist!</p>;
},

Your Example Website or App

localhost.com

Steps to Reproduce the Bug or Issue

error appears as soon as app starts

Expected behavior

Error message to disappear:

Warning: A notFoundError was encountered on the route with ID "root", but a notFoundComponent option was not configured, nor was a router level defaultNotFoundComponent configured. Consider configuring at least one of these to avoid TanStack Router's overly generic defaultNotFoundComponent (

Not Found

)

A summary of the changes CodeRabbit can apply:

• Confirm the warning is intentional (not a bug), recommend documenting/closing the issue, and apply a typo fix by replacing (<div>Not Found<div>) with (<div>Not Found</div>) in packages/react-router/src/renderRouteNotFound.tsx and packages/solid-router/src/renderRouteNotFound.tsx.

• Update packages/react-router/src/renderRouteNotFound.tsx and packages/solid-router/src/renderRouteNotFound.tsx to fix a typo in the development warning message by replacing the malformed HTML snippet "

  Not Found

  " with the correct "

  Not Found

  ", so the warning shows valid markup.

this error most likely comes from the browser trying to load non existing stuff like https://gebna.gg/blog/annoying-well-known-appspecific-com-chrome-devtools-json-request

then a not-found page will be rendered that needs a not found component.
