Hello, add your code with the error if you want more help. With the context, we can understand and help with that 😄

The error message "Element type is invalid. Received a promise that resolves to: undefined. Lazy element type must resolve to a class or function" occurs in React when you try to use the lazy function to dynamically import a component, but the imported module does not contain a default export.

The lazy function is used to dynamically import a component and render it only when it is needed, which can improve the performance of your application by reducing the amount of code that is loaded up front. However, in order for this function to work, the imported module must have a default export that resolves to a React component (i.e. a class or function).

To fix this error, you will need to ensure that the imported module has a default export that resolves to a React component. Here is an example of how you might do this:

// In MyComponent.js
import React from 'react';

export default function MyComponent() {
  return <div>My component</div>;
}

// In App.js
import React, { lazy } from 'react';

const MyLazyComponent = lazy(() => import('./MyComponent'));

function App() {
  return (
    <div>
      <MyLazyComponent />
    </div>
  );
}

In this example, the MyComponent module is exported as the default export, which means that it can be imported and rendered using the lazy function in
