Using LanguageServer.jl with eglot in emacs

This sounds all kinds of awesome… I’m a more or less old-school emacs user and haven’t kept up with newer emacs features… How do I get this installed effectively?

I installed eglot-jl from MELPA, am in a julia buffer with julia mode and company mode on, and I get:

[jsonrpc] Server exited with status 1
error in process sentinel: eglot--error: [eglot] -1: Server died
error in process sentinel: [eglot] -1: Server died

Running julia 1.4.1 and emacs-gtk 1:26.3+1-2 on Debian testing.
