+HLS is not yet able to find project preprocessors, which may result in `could not execute: <preprocessor>` errors. This problem is
 tracked in https://github.com/haskell/haskell-language-server/issues/176 and originally comes from https://github.com/mpickering/hie-bios/issues/125
 
 As a workaround, you need to ensure the preprocessor is available in the path (install globally with Stack or Cabal, provide in `shell.nix`, etc.).
