Can't Override Next Props

Why This Error Occurred

In your pages/_app.js you returned an object from getInitialProps that contained a router or Component value. These property names are used by Next.js and can not be overwritten.

Possible Ways to Fix It

Look in your _app.js component's getInitialProps function and make sure neither of these property names are present in the object returned.
