Cannot allocate color 0

[igorsol]

When I try to start Vim with aurora colorscheme I see these errors:

Error detected while processing /home/user/.vim/bundle/coc.nvim/plugin/coc.vim[455]..function <SNR>27_Hi[51]..<SNR>27_AddAnsiGroups:
line   18:

line    3:
E254: Cannot allocate color 0
Press ENTER or type command to continue

After pressing ENTER several more lines with error messages appear:

Is it with termguicolors ?

[igorsol]

Yes I have this in my vimrc:

if has('termguicolors')
  set termguicolors
endif

And I believe it works correctly because I have many other colorschemes working.

Probably this similar error will be useful for debugging: https://github.com/dracula/vim/issues/93

Issue should have been fix in the latest version. It is related to vim and I am using neovim for more than a year and did not see this issue.

I can confirm: now it works. Thanks!
