You need to enable javascript to run this app react using yarn start

I cloned an existing ReactJS app with version 16.12.0. I installed the app using yarn install and while running the app using yarn start. The app loads NoScript text You need to enable JavaScript to run this app..

How to solve this issue?

Is javascript enabled in your browser?

If you visit https://www.enable-javascript.com/ do you see Javascript is disabled in your web browser. If you enable JavaScript, this text will change or Javascript is enabled in your web browser. If you disable JavaScript, this text will change.

If you see Javascript is disabled in your web browser. If you enable JavaScript, this text will change, follow the instructions on the same page just below that message to enable javascript, and try your app again.

I had the same error when I used BrowserRouter instead of RouterProvider. This code didn’t work:

const router = createBrowserRouter([{ path: "/", element: <div>Test page</div> }]);
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(  
  <React.StrictMode>    
    <BrowserRouter router={router} />
  </React.StrictMode>
);

this code did work:

const router = createBrowserRouter([{ path: "/", element: <div>Test page</div> }]);
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(  
  <React.StrictMode>    
    <RouterProvider router={router} />
  </React.StrictMode>
);
