Cannot access `AsyncLocalStorage` when using default fetch export API

I’m getting an AsyncLocalStorage issue after updating my package @domcojs/vercel to utilize the new default fetch export API for the function. Instead of converting Web to Node within the package, the build just exports an object with a web standard fetch method now instead.

You can see the error occur here.

Context.get is calling AsyncLocalStorage.getStore within the ovr package.

Works in dev, preview, and my prerendered pages during build are rendered correctly.
