react redux next.js javascript

I've searched everywhere and can't find a clear answer... I'm trying to figure out I'm working on a project and hit a roadblock..... I'm not sure how to approach I'm sure I'm missing something obvious here, but I'm confused about I've been banging my head against this for hours. I'm experiencing an issue where my React component does not update correctly after the Redux state changes. I'm using Redux Toolkit for state management in a Next.js application. I have a component that displays user data based on the Redux state, but after dispatching an action to update the user information, the component doesn't re-render as expected. Here’s the relevant part of my Redux slice: ```javascript import { createSlice } from '@reduxjs/toolkit'; const userSlice = createSlice({ name: 'user', initialState: { data: null }, reducers: { setUser(state, action) { state.data = action.payload; }, }, }); export const { setUser } = userSlice.actions; export default userSlice.reducer; ``` In my component, I'm using the `useSelector` hook to get the user data: ```javascript import React from 'react'; import { useSelector, useDispatch } from 'react-redux'; import { setUser } from '../slices/userSlice'; const UserProfile = () => { const dispatch = useDispatch(); const user = useSelector((state) => state.user.data); const updateUser = () => { // Simulate a user update from an API call const newUserData = { name: 'John Doe', age: 30 }; dispatch(setUser(newUserData)); }; return ( <div> <h1>User Profile</h1> {user ? <p>{user.name}, {user.age}</p> : <p>No user data</p>} <button onClick={updateUser}>Update User</button> </div> ); }; export default UserProfile; ``` The user data should update and re-render the component when the button is clicked, but it seems the component doesn't reflect the new data. I’ve ensured that my Redux store is properly configured and has the necessary middleware applied. I also verified that the `setUser` action is being dispatched as expected with the correct payload. In the console, I see the following warning sometimes: `Warning: Can't perform a React state update on an unmounted component`. I'm not sure why this is happening since the component should still be mounted when I'm dispatching the action. Has anyone else encountered this issue? What could be the reason for the component not re-rendering, and how can I resolve it? Any insights would be greatly appreciated! I'm working on a web app that needs to handle this. For context: I'm using Javascript on macOS. Thanks in advance! My development environment is Linux. Thanks in advance! I'm working with Javascript in a Docker container on Debian. I'm developing on Windows 11 with Javascript. Thanks for your help in advance! I'm developing on macOS with Javascript. I'd be grateful for any help. For reference, this is a production REST API.
