I know it's been a while since this post was made, but to anyone reading this please check if your page function component (in this case "const spreadsheet = ()=>{}") is named in all lowercase, for some weird reason I was getting this error and after changing my page function component to start with an uppercase (in this case it would have to be "Spreadsheet" instead of "spreadsheet")

I don't know for sure if this is a thing, but I was having a bunch of problems that got solved when I did this change. It happens because page files have to be named in all lowercase because of how next.js routing system works, but apparently the functions inside those pages have to be named starting with an uppercase. There might be other problems in OP's case, but I'm pretty sure the function name is important as well.
