Description

Hello, i am using react starter kit and trying to replace reactdom with rapscallion. butt i getting this error

Unhandled rejection TypeError: Unknown node of type: undefined
    at traverse (.......\node_modules\rapscallion\lib\render\traverse.js:373:9)
     at renderChildrenArray (\node_modules\rapscallion\lib\render\traverse.js:57:7)

I tried to replace a part

const html = ReactDOM.renderToStaticMarkup(<Html {...data} />);
 res.status(route.status || 200);
 res.send(`<!doctype html>${html}`);

with

const html = rapscallion.render(<Html {...data} />);
 let responseTemplate = rapscallion.template`<!doctype html>${html}`;
 responseTemplate.toStream().pipe(res);

any suggestion?

Research direction
Investigate the error in rapscallion's traverse.js file at line 373. The error occurs when an undefined node type is encountered. Check if the user's replacement code or the React elements being rendered contain unsupported node types. Review rapscallion's documentation or source to see if it supports all React node types that ReactDOM.renderToStaticMarkup does. Consider adding a fallback for unknown node types or providing a clearer error message.
