Incorrect Error: "module term's arity should be zero"

Hello, the language server seems to be incorrectly highlighting the import_module. The compiler still runs, so it seems like a parsing error from the language server.

I have the exact same issue, I assume from the same tutorial. https://mercurylang.org/documentation/papers/book.pdf

I'd be interested in knowing where I look in the source code this is dealt with.
