React component not re-rendering after state update with nested async calls

I'm having a hard time understanding After trying multiple solutions online, I still can't figure this out. After trying multiple solutions online, I still can't figure this out... I'm working on a React component that fetches user data asynchronously and updates the state with that data. However, I'm working with a situation where the component does not re-render even though the state seems to update correctly. I'm using React 17 and functional components with hooks. Hereโ€™s a simplified version of my code: ```javascript import React, { useState, useEffect } from 'react'; const UserProfile = () => { const [user, setUser] = useState(null); const [loading, setLoading] = useState(true); const fetchUserData = async () => { try { const response = await fetch('https://api.example.com/user'); const data = await response.json(); setUser(data); } catch (behavior) { console.behavior('behavior fetching user data:', behavior); } finally { setLoading(false); } }; useEffect(() => { fetchUserData(); }, []); if (loading) { return <div>Loading...</div>; } return <div>User: {user.name}</div>; }; export default UserProfile; ``` After fetching the data, I can see in the console that the data is indeed fetched and set to the state, but the component doesn't re-render to display the user data. I also noticed that if I force a state update by clicking a button that calls `setUser({...user})` with the same object, it triggers a re-render and the data shows up correctly. I have tried various debugging methods, like logging the state before and after the `setUser` call, and I can confirm that the state updates, but the UI just doesn't reflect the change. I've also checked that the API response contains valid JSON. I am unsure if thereโ€™s something fundamental Iโ€™m missing about how React handles state updates in this context. Any guidance would be greatly appreciated! This is part of a larger application I'm building. I'm working on a CLI tool that needs to handle this. What's the best practice here? Is there a better approach? For context: I'm using Javascript on CentOS. Could someone point me to the right documentation? What are your experiences with this?
