Description

When I use this grammar file: https://github.com/pragmagic/vscode-nim/blob/master/syntaxes/nim.json for the nim language, I got a NPE:

when I open the file (Attachement example.nim).

Steps to reproduce:

Open options
Go to Editor -> Language Server
Create a new entry for ".nim" files
Add the textmate file from the link in this description
Save the entry and apply the options
Open the example.nim file
See no syntax highlighting and see the NPE as mentioned.
