I apologize for not knowing what caused this issue. Could be related to me opening or creating a file. I'm working on a repro

Sounds like you made an input query and then tried to use it like an on-demand one. Input queries have to have a value in them before you can read one.

This is a rust-analyzer bug. Not a salsa bug.
