Racket - Language Server Exited

I created a simple example.rkt file and when I edit it with Helix the language server immediately exits.

For what it's worth, I'm now suffering from the same issue...

EDIT: I've now solved it by running raco pkg install racket-langserver — perhaps that step can be automated somehow? Or the health-check could be updated to look for it?
