How to fix "TypeError: Cannot read properties of undefined (reading 'useSystemColorMode')"


So I am using ChakraUI and React JS to make a project. Whenever I start the project it gives me the error, "TypeError: Cannot read properties of undefined (reading 'useSystemColorMode')".
I didn't edit any global theme or anything in chakra. I just started making the navbar, designed with CSS. And when I try to run it, it shows me the error. here is my navbar component

import React from "react";
import { MenuItems } from "./MenuItems";
import "./navbar.css";

function Navbar() {
  return (
    <>
      <nav className='NavbarItems'>
        <h1 className='navbar-logo'></h1>
        <div className='menu-icon'></div>
        <ul>
          {MenuItems.map((item, index) => {
            return (
              <li key={index}>
                <a className={item.cname} href={item.url}>
                  {item.title}
                </a>
              </li>
            );
          })}
        </ul>
      </nav>
    </>
  );
}

export default Navbar;

Navbar CSS file

.NavbarItems {
  height: 80px;
  display: flex;
  justify-content: center;
}

App.js file

import { ChakraProvider } from "@chakra-ui/provider";
import Navbar from "./components/navbar";
function App() {
  return (
    <ChakraProvider>
      <Navbar />
    </ChakraProvider>
  );
}

export default App;

Solution

  • So basically this is a problem with ChakraUI theme,even though I did not do anything with ChakraUI theme or whatsoever. I added theme.js file which included the following:

    // theme.js
    
    // 1. import `extendTheme` function
    import { extendTheme } from "@chakra-ui/react";
    
    // 2. Add your color mode config
    const config = {
      initialColorMode: "light",
      useSystemColorMode: true,
    };
    
    // 3. extend the theme
    const theme = extendTheme({ config });
    
    export default theme;
    

    then I included the following in index.js file:

    import React from "react";
    import ReactDOM from "react-dom";
    import App from "./App";
    import { ColorModeScript } from "@chakra-ui/color-mode";
    import theme from "./theme";
    
    ReactDOM.render(
      <React.StrictMode>
        <ColorModeScript initialColorMode={theme.config.initialColorMode} />
        <App />
      </React.StrictMode>,
      document.getElementById("root")
    );
    

    And it worked. If anyone facing the same problem, you can check out https://chakra-ui.com/docs/features/color-mode.
