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)

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?

Contributor guide

Research direction
Inspect the error stack trace to identify which React element type is undefined when Raps callion tries to traverse the virtual DOM. Look for components that may be returning undefined or null, or check if any dynamic import or conditional rendering results in an undefined type.
