Try disabling prerendering with --no-prerender. We prerender your application in Node, so you need to ensure everything will work outside of the browser.

@rschristian Thanks a lot. Worked.

[rschristian]

Glad to hear it. Now that you know the issue, what you can do is wrap the offending code in window checks, i.e., if (typeof window !== "undefined") { ... }. This way you can still get all the benefits of prerendering, while skipping the bits that won't work in Node environments.

awesome :) thanks
