Type cast in one line arrow function `() => ({} as Type)` cause vite:esbuild transform error

[daolanfler]

Describe the bug

Type cast in useMemo () => ({} as Type) cause vite:esbuild transform error.

code:

  const v = useMemo(
    () =>
      ({
        name: 'random',
        age: count,
      } as RandomType), // type cast here will cause error
    [count]
  );

  // if not cast to `RandomType` in `()` return , its ok
  const v2 = useMemo<RandomType>(
    () => ({
      name: 'random',
      age: count,
    }),
    [count]
  );

error msg:

10:34:53 [vite] hmr update /src/App.tsx

similar code like below doesn't cause error in vanilla vite, but errors with this plugin

  const fakeMemo = (fn: any, dep: []) => fn(dep);
  const v3 = fakeMemo(
    () =>
      ({
        name: 'random',
        age: count,
      } as RandomType),
    []
  );
