react-router-dom - TypeError: Cannot read properties of undefined (reading 'pathname')

Question

While using react-router-dom 5.3.0, I am opening a modal but am not changing route, and this error appears.

I have since downgraded react-router-dom to 5.2.0 and this error does not appear.

Any help is much appreciated :-)

Hi @BENARDPatrick, could you expand a bit more, I'm not sure what to do with this in terms of my code. — docgecko

You see the second stack trace error ? line 104 createPath(context.location) ? It calls the function createPath and inside it, the line 47 location is undefined. So context.location is undefined.... In your code, you can wait that context.location has a wanted value... — BENARD Patrick

Thanks @BENARDPatrick. All of these errors take place within a package (which I believe is react-router-dom) in my node_modules. So I was thinking that the problem lies in the package? — docgecko

Anyway, I just upgraded react-router-dom again to the latest version and I can't actually replicate the problem, lets see if the problem has now gone. — docgecko

I had the same error after upgrading the react-router-dom version when I tried accessing the current URL with location.pathname .

Using the useLocation() hook solved my problem:

import { useLocation } from 'react-router-dom';

// getting current pathname with custom hook

const useName = () => {
const location = useLocation();
return location.pathname;
}
