The second argument is wrong in the function hl of the build_tmTheme module #22

I've installed this plugin for the first time, but when I try to run it, the following error appears.

I looked into the code and noticed this statement tries to get the background value.

I've printed the value of vim.api.nvim_get_hl_id_by_name("Normal", true) and I received one value the foreground one. It means the background one doesn't exist.
