Thanks for making this! I did run into this error though.

Can you provide details about your Neovim client and version.

If I was to guess I suspect you may be running an older version of Neovim. To-be-confirmed.

Neovim 0.4.3 works fine for me, for reference.

Ultimately this should be fixed. I just need details to repeat it. Thanks.

This issue is now fixed in that latest commit, please update and try again.

It seems the ext_termcolors attribute is only set for Neovim client 0.4 and later. For older Neovim clients I no longer do the termguicolors test; however it should be pretty obvious that something is wrong if a user doesn't set it (for terminal-based Neovim).

Thank you! Works great :)
