No Router Instance

Why This Error Occurred

During Prerendering (SSR or SSG) you tried to access a router method push, replace, back, which is not supported.

Possible Ways to Fix It

In a function Component you can move the code into the useEffect hook.

In a class Component, move any calls to router methods to the componentDidMount lifecycle method.

This way the calls to the router methods are only executed in the browser.
