Crash on start: List index out of range

[Yeray Díaz]

Hello, thanks for the work on LSP-elixir 🙏🏻

I'm having trouble installing it, although it seems some of the functionality does work. Specifically, shortly after starting ST4 I get a dialog saying:

Could not start elixir-ls
list index out of range
Server will be disabled for this window

When I open the console there's the following output:

Failed to register plugin ""
Traceback (most recent call last):
  File "/Users/yeray/Library/Application Support/Sublime Text 3/Installed Packages/LSP.sublime-package/plugin/core/sessions.py", line 602, in _register_plugin_impl

I tried digging a bit and get a root cause but I don't have a lot of experience with ST plugins and LSP. I'd be happy to have a look myself with some guidance though.

Thanks again.

Update: I forgot to include some details about my system:

• Mac OS X Catalina
• ST4 build 4099

After reinstalling the packages the error is not happening anymore.
