Server keeps crashing in NeoVim with CoC

I’m trying to get this running with NeoVim and CoC. But the server keeps crashing.

Current Behavior

This is what I see with :CocOpenLog

Steps to Reproduce (for bugs)

• Install the language server via npm
• Install NeoVim
• Follow the instructions for adding CoC and the Coc configuration from https://github.com/elm-tooling/elm-vim

Your Environment

• Version used:

~ $ elm-language-server -v
1.4.4

• Environment name and version (e.g. node.js 5.4):

~ $ node --version
v10.17.0

~ $ elm --version
0.19.1

• Editor used:

~ $ nvim --version
NVIM v0.3.8

• Operating System and version:

~ $ uname -a
Linux pop-os 5.3.0-22-generic #24+system76~1573659475~19.10~26b2022-Ubuntu SMP Wed Nov 13 20:0 x86_64 x86_64 x86_64 GNU/Linux

Anyway I can get more information about what is going on in the node package? Thanks

It is working fine in both. Well except that in elm-spa-example is substantially faster as is a small source. But that is another issue.

So it works fine for elm-spa-example, but not your internal app?
