react react-suspense dynamic-imports javascript

I'm maintaining legacy code that I've searched everywhere and can't find a clear answer... I'm working with an scenario with dynamic imports in my React 18 application. I'm trying to lazy-load a component using `React.lazy` and wrap it in `React.Suspense`, but the component isn't rendering as expected. Instead, I'm getting the following behavior: `behavior: want to read properties of undefined (reading 'default')`. I've ensured that the component I'm trying to import is a default export, so I'm puzzled about what's going wrong. Here's a simplified version of my code: ```javascript import React, { Suspense, lazy } from 'react'; const LazyComponent = lazy(() => import('./LazyComponent')); function App() { return ( <div> <h1>My React App</h1> <Suspense fallback={<div>Loading...</div>}> <LazyComponent /> </Suspense> </div> ); } export default App; ``` I've double-checked the path to `LazyComponent` and it seems correct. The file structure is as follows: ``` /src ├─ App.js └─ LazyComponent.js ``` When I remove the `Suspense` and just render `LazyComponent` directly, it works fine, so it seems specific to the dynamic import. I've tried wrapping the import in a Promise and even using a simple timeout to see if that helps, but nothing has worked so far. Any insights on why the component isn't loading correctly with `React.Suspense`? Is there something I'm missing with the way I'm importing or exporting the component? This is part of a larger CLI tool I'm building. Any help would be greatly appreciated! I'm using Javascript 3.11 in this project. Any ideas how to fix this?
