Language Server throwing MethodError

[jarbus]

Julia's Language Server has worked for me in the past, but is now throwing this error after a re-install and I can't figure out what's going on. Using the latest version and currently testing without an editor so I can catch debug info.

julia> using LanguageServer, LanguageServer.SymbolServer; runserver()

What version of Julia are you using? I suspect it's 1.7.0-beta, which is not guaranteed to be compatible. Try the latest master (add LanguageServer#master).

I'm using 1.6.3. I followed the install instructions for vim, so running

julia --project=/home/jack/.julia/environments/nvim-lspconfig --startup-file=no --history-file=no -e 'ls_install_path = joinpath(get(DEPOT_PATH, 1, joinpath(homedir(), ".julia")), "environments", "nvim-lspconfig"); pushfirst!(LOAD_PATH, ls_install_path);  using LanguageServer; popfirst!(LOAD_PATH); depot_path = get(ENV, "JULIA_DEPOT_PATH", ""); project_path = let; dirname(something( Base.load_path_expand(( p = get(ENV, "JULIA_PROJECT", nothing); p === nothing ? nothing : isempty(p) ? nothing : p )), Base.current_project(), get(Base.load_path(), 1, nothing), Base.load_path_expand("@v#.#"), )) end;   @info "Running language server" VERSION pwd() project_path depot_path;    server = LanguageServer.LanguageServerInstance(stdin, stdout, project_path, depot_path);    server.runlinter = true;    run(server)'

Yields a process that hangs on the following message on the master branch

[ Info: Received new data from Julia Symbol Server.

Is this the intended behavior?

I think it would be helpful to fully state your environment:

1. julia version and platform
2. client (vim or neovim? what version? which language client)
3. minimal example (Project.toml for the julia package you're working on and for your global environment)
4. Exact reproducing steps (consolidated, in your issue description if you weren't using master before) together with the error message and the full log (if available).

I was getting the same error as @jarbus using LanguageServer v4.1.0. Switching to #master (4.1.1-DEV) did resolve the error for me, but I am using julia v1.7.0rc2.

Actually LanguageServer.jl seems to work now, I think it only crashes on scripts without an associated Project.toml file. Thanks for the help!
