Bug report

Describe the bug

Don't know what happened inside next.js, prompting error I don't understand. Hope someone could point me a direction that I might know where to find the problem. Thanks

I'm getting this:

I resolve this issue myself, I accidentally assign window variable to a blank {}, which will make things break when server-side rendering.
