Link to the code that reproduces this issue or a replay of the bug

To Reproduce

Just open the reproduction example.

Describe the Bug

1. Can't import "server-only" files into middleware.

2. Importing "use server" files into middleware handles it as client file. So for example environment isn't available and code that relies on it breaks.

Expected Behavior
