Example: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.

## Description

This issue usually happens when you're trying to apply state 
changes to a component that does not exists anymore.

Often happens when the component gets removed from a tree
while there is a promise running in one of it's lifecycles.

The best way to fix it is to make sure that if there is any
promises in your component lifecycle, it should abort those
once the component gets unmounted from the tree.
