Steps to reproduce

What is Expected?

The Host should display 2 component showing list of Pokémon.

What is actually happening?

page is empty and Console has multiple errors:

Warning: lazy: Expected the result of a dynamic import() call. Instead received: () => {
  const [, addPokemons] = useAtom(addAllPokemons);
  const [pokemons$1] = useAtom(pokemons);

  const fetchPokemons = async () => {

    );
    const jsonData = await response.json();
    addPokemons(jsonData);

Hey!

I had a similar issue. When you have multiple exposes in MFE the module federation plugin automatically changes the export in the federation entry point and then you don't have a default export.

In my case, the below fixes the issue, and modules were loaded correctly when there was a single or multiple exposes.

const remote = await federation.__federation_method_getRemote(moduleName, exposeName);
return "default" in remote ? remote : { default: remote };

thank you, it worked! :)
