Next Unhandled runtime error. No router instance found
I was making a portfolio in Next and i made just a header to show in all pages by putting it on _app.js, just that, never touched the _document.js. This is the error:
Unhandled Runtime Error Error: No router instance found. You should only use "next/router" inside the client side of your app. .next\static\chunks\fallback\main.js (116:10) @ getRouter
Here’s the _app.js code

This solved the problem:
I was in "d/projects/. " instead of "d/Projects/. ".
Make sure when running your NextJS project that you are in the correctly cased filepath. My problem was that I was in the directory "react/next-project" instead of "React/next-project".

Установил 3.1, удалил папку install. Захожу по ссылке или по адресу, набирая:
. адрес.рф/forum/
форум открывается, но адресная строка меняется на:
. адрес.рф/forum/install/index.php
и а внизу пишет: No route found for «GET /install/index.php»
Почему так? И как исправить? Подскажите, пожалуйста.

Всем спасибо! Все вдруг само заработало. Это что-то мой хостер недоделал. Позавчера он перенес мой хостинг сервера с MySQL 4.0 на другой физический сервер с MySQL 5.1 Пять дней (и пять лет) переносили.
Next.JS Error: No router instance found
I ran into a stupid problem I created for myself. And then I solved and that made me realize a thing about Next.JS and the server side rendering features of this framework.
I wanted to share my failures and solution to the problems I created here.
I have a page that is server-side rendered, since I’m the getServerSideProps .
One of the components on the page, reach out and grabs the router:
And I then added a click-handler like this:
And it blew up, with a very nice, but ultimately not helpful error message:
Error: No router instance found. you should only use “next/router” inside the client side of your app.
So this error even has an page on the Next.JS site and it’s helpfully trying to tell me that I’m using the router on the server-side. It also sent me down the wrong route (hehe sorry) to try to create the routing in the useEffect hook.
When in fact the solution was much easier
The solution — declare the function. Don’t call it
As I’ve written the function now, the router.push(‘/’) will be called on server-side rendering, since I’m invoking the router.push But that’s not what I want. I want it to be called when the user clicks. This should be done like this:
And I had one of those …. BUT OF COURSE.
But then I realized how much sense it made — the server side rendered version should just render the function to be executed when the user clicks the div. Not execute the function. A bit like the difference of declaring a callback and actually calling it.
A simple slip-up but the reflection made me think about what server side rendering is and I learned some more. WIN.
«No router instance found.» error when setting Router.beforePopState in pages/_app.js #4289
Router.beforePopState should be easy to set. The code should reside in pages/_app.js with client-side only guard since it should be run on client only once.
Current Behavior
I put up an example repository here.
Server-side went ok without an error, but browsers complain with the following.
Steps to Reproduce (for bugs)
Context
See «Expected Behavior» above.
Your Environment
The text was updated successfully, but these errors were encountered:
I fixed the issue by moving the usage of Router.beforePopState into App#componentDidMount. I’ll close this. Thanks for any concerns.
hi @peacefullybound i did move it to componentDidMount lifecycle but unfortunately it still didnt work whenever i changed the route, any thought tho?
What do you mean exactly by «still didnt work»? @afganhalbana I think you should open a separate issue if it’s not the same as «No router instance found.»
@peacefullybound Well at first i did have the same problem as yours, and after move that code to componentDidMount in _app.js the error disappear, but unfortunately it’s still not working as well without any error informed on the dev console, here is my componentDidUpdate code:
my next version is 6.0.3, please share how you solved this issue
@afganhalbana Facing the same issue, any luck with it?
I solve my problem by checking first if Router wasn’t undefined.
const pathname = Router ? Router.pathname : »
The solution was inconsistent though, as sometimes the error came back. So a better option is to use withRouter and check on the props for the current pathname. Example
