System Info

OS : Ubuntu 24.04
Browser : Chrome

Used Package Manager

npm

Expected Behavior

The build should succeed when using the @netlify/vite-plugin-react-router package in combination with defined pre-render routes in react-router.config.ts . I expect the plugin to work smoothly with Vite and React Router, enabling proper deployment to Netlify without build failures.

Actual Behavior

When I include the @netlify/vite-plugin-react-router plugin in vite.config.ts and have pre-render routes defined, the build fails and throws an error. However, the build succeeds if I either remove the plugin or remove the pre-render routes from react-router.config.ts, which defeats the purpose of pre-rendering routes for better performance.

Closing as a dup of #14074/#13226. Please feel free to open a discussion if you'd like to see this feature (prerendering with more advanced custom servers/plugins) considered.
