I don't see any obvious errors with the implementation. maybe I'm not getting your question right - are you saying cancel is called right away when the component is still mounted? that shouldn't happen since you provided [] to useEffect which means it'll only run once and the clean up function is only called when the component unmounts (similar to componentDidMount + componentWillUnmount).
one quick things though: hook names should start with use - instead of GetReqHandler you probably want to rename it do useGetReqHandler.
Another thing to note is if you have hot module reloading - your page might unmount and re-mount the component which will cause cancellations - but if you are not doing that, I don't think the problem is here, you might want to check if your code works properly if you change it to a class component.
Sorry for my late response.

Yea i thnik this is the problem.
instead of codesandbox here is the project on gitlab
React Project
the useGetReques used under home/abonne/abonne.js
and it's parent is home/home_container.js
if you could suggest a solution to solve this problem using hooks or i any kind of parameters.
Sorry again - would you mind adding me to that project? my gitlab handle is @pallymore
Thanks
I have solve it, i had to change the root component of routes to class instead of fuctional component and it solved the problem
