Error: TypeError

An error of TypeError occurred, indicating that the code attempted to access properties of a null object, specifically the useContext property.

The useContext function in React is used to consume a context provided by a Context.Provider component. It allows functional components to subscribe to context changes and access the context values.

In order to use the useContext function, make sure:

  • A context has been created using React.createContext().
  • A Context.Provider component wraps the component using useContext.
  • The useContext function is called within the component where the context values are needed.

Here’s an example where useContext is used to access the value from the context: 


    // Create a context
    const MyContext = React.createContext();

    // Wrap the component using the context provider
    function App() {
      return (
        <MyContext.Provider value="Hello, World!">
          <ChildComponent />
        </MyContext.Provider>
      );
    }

    // Consume the context value using useContext
    function ChildComponent() {
      const value = React.useContext(MyContext);
      return <p>Context value: {value}</p>;
    }

Make sure that the context is properly provided by the provider component, and that the component using the useContext hook is placed within the provider’s scope. If the error persists, check if the component is rendered without any null values or ensure that the object being accessed is not null before accessing its properties.
