@sphyrnidae8 I don't think it is lazy.nvim specific error. Just paste the whole gist code , in place of require("plugins.feline").
Or create files init.lua, dharmx.lua in lua/plugins/feline/ and call it by require("plugins.feline.dharmx") in feline/init.lua

Have started getting this error:

vim.lsp.util.get_progress_messages() is deprecated, use vim.lsp.status() instead. :help deprecated Feature will be removed in Nvim 0.11

Its the usage of this function. Any chance of a quick fix/update?
