How to fix Invariant failed: could not find react-redux context value in React

ReactINTERMEDIATEMEDIUM

This error occurs when React-Redux hooks like useSelector or useDispatch are called outside of a Provider component. The fix involves wrapping your component tree with <Provider store={store}> or ensuring custom context hooks are used correctly.

What this error means

React-Redux uses React's Context API to provide the Redux store to components throughout your application. When you call hooks like `useSelector` or `useDispatch`, they look for the Redux store in the nearest React-Redux context. The error "Invariant failed: could not find react-redux context value" means that a component is trying to access the Redux store, but there's no Provider component higher up in the component tree that supplies the store context. This typically happens when: 1. You forget to wrap your app with the Redux Provider 2. You're using hooks in a component that's rendered outside the Provider tree 3. You have multiple React/React-Redux instances causing context mismatch 4. You're using custom contexts incorrectly The Provider component creates the React context that holds your Redux store, and all hooks depend on finding this context value. Without it, React-Redux cannot connect to your store.

How to fix "Invariant failed: could not find react-redux context value"

1Wrap your app with Redux Provider

Ensure your entire React application is wrapped with the Redux Provider component. In your main entry file (usually index.js, App.js, or _app.js in Next.js):

jsx

import React from 'react';
import ReactDOM from 'react-dom/client';
import { Provider } from 'react-redux';
import { store } from './app/store';
import App from './App';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <Provider store={store}>
    <App />
  </Provider>
);

For Next.js with App Router:

jsx

// app/providers.tsx
'use client';

import { Provider } from 'react-redux';
import { store } from '@/lib/store';

export function Providers({ children }: { children: React.ReactNode }) {
  return <Provider store={store}>{children}</Provider>;
}

// app/layout.tsx
import { Providers } from './providers';

export default function RootLayout({ children }) {
  return (
    <html lang="en">
      <body>
        <Providers>{children}</Providers>
      </body>
    </html>
  );
}

2Check component hierarchy

Verify that every component using Redux hooks is a descendant of the Provider. Common issues:

1. Modal/dialog components that render via ReactDOM.createPortal or similar
2. Third-party components that might render outside your tree
3. Dynamic imports that load components separately

For portals or similar cases, ensure the portal target is still within the Provider:

jsx

// Modal component that uses Redux
function MyModal() {
  const data = useSelector(state => state.modal.data); // This needs Provider!
  // ...
}

// App component
function App() {
  return (
    <Provider store={store}>
      {/* Modal renders here via portal, but portal target is inside Provider */}
      <div id="modal-root"></div>
      <MainContent />
    </Provider>
  );
}

3Fix duplicate React/React-Redux dependencies

Multiple copies of React or React-Redux can cause context mismatch. Check with:

bash

npm ls react react-redux
# or
yarn why react react-redux

Solutions:

1. Use peerDependencies in shared packages:

json

// In your shared package's package.json
{
  "peerDependencies": {
    "react": "^18.0.0",
    "react-redux": "^9.0.0"
  },
  "devDependencies": {
    "react": "^18.0.0",
    "react-redux": "^9.0.0"
  }
}

2. Add resolutions in main app (Yarn):

json

{
  "resolutions": {
    "react": "^18.0.0",
    "react-redux": "^9.0.0"
  }
}

3. Use Webpack aliases:

// webpack.config.js
module.exports = {
  resolve: {
    alias: {
      react: path.resolve(__dirname, 'node_modules/react'),
      'react-redux': path.resolve(__dirname, 'node_modules/react-redux')
    }
  }
};

4Use correct imports and custom contexts

Import from main package:

// Correct
import { useSelector } from 'react-redux';
// Wrong
import { useSelector } from 'react-redux/es/connect/connect';

For custom contexts:
If you're using a custom React-Redux context, you must use the corresponding custom hooks:

jsx

import { createStoreHook, createDispatchHook } from 'react-redux';
import { MyContext } from './my-context';

// Create custom hooks for your context
const useStore = createStoreHook(MyContext);
const useDispatch = createDispatchHook(MyContext);

function MyComponent() {
  const store = useStore(); // Uses custom context
  const dispatch = useDispatch();
  // ...
}

// Wrap with custom Provider
<Provider context={MyContext} store={store}>
  <App />
</Provider>

Using default hooks with a custom context Provider will cause this error.

5Fix testing setup

When testing components that use Redux hooks, wrap them in Provider:

jsx

// With React Testing Library
import { render } from '@testing-library/react';
import { Provider } from 'react-redux';
import { store } from './store';
import Component from './Component';

test('renders component', () => {
  const { getByText } = render(
    <Provider store={store}>
      <Component />
    </Provider>
  );
  // ...
});

// Or create a custom render function
function renderWithProviders(ui, options = {}) {
  const { store = createStore(), ...renderOptions } = options;
  function Wrapper({ children }) {
    return <Provider store={store}>{children}</Provider>;
  }
  return { store, ...render(ui, { wrapper: Wrapper, ...renderOptions }) };
}
