Error running config for indent-blankline.nvim

[munim]

I am trying to use your config and cloned your repo into ~/.config/nvim/lua/user. Seems like everything working but when I start Neovim, I see the below errors:

packer.nvim: Error running config for indent-blankline.nvim: [string "..."]:0: attempt to index a boolean value

I am using Neovim 0.7 (AppImage downloaded from official repository) with Astro Vim v1.4.3-1-g7363a43. I have also tried to use your neovim-0.7 branch as well but the same error persists.

Any idea?
