vim-jsonc shows error:

 "modules-left": [                
   //"custom/name",
   "sway/workspaces",
   "custom/weather",
   "sway/mode"
   //"custom/right-arrow-dark"
 ],

vim-jsonc does NOT shows error

 "modules-left": [                
   //"custom/name",
   "sway/workspaces",
   "custom/weather",
   //"custom/right-arrow-dark"
   "sway/mode"
 ],

I am using NeoVIM: NVIM v0.4.4 on Debian
