Having problem with my React Native App: Can't perform a React state update on an unmounted component

Question

I am new to React and I am getting this error. Can anyone help me on how to sort this. Thanks!

Full Warning Statement: Warning: 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.

Sample code:

    useEffect(() => { 
    fetchBlogs();
    const subscription = DataStore.observe(Blog).subscribe(() => fetchBlogs());
    return ()  =>{
        subscription.unsubscribe();
    };

}, [])


async function fetchBlogs() {
    const blogData = await DataStore.query(Blog);


    const sortedBlogs = blogData.sort((a,b) =>  b.createdAt > a.createdAt);


     if (findTrueItem(sortedBlogs) !== undefined)
    {  
         arrayMove(sortedBlogs,findPosition(sortedBlogs), 0);
     }
    
    setBlogs(sortedBlogs);
}
