I had the same issue with LSPs. If you have LSP configurations in a dedicated lsp directory all you need to do is instead of calling this:

vim.lsp.config(<lsp server>, config)

just return the config as a table i.e

vim.lsp.config("emmet_ls", { filetypes = { "html", "css", "sass", "scss", "less", "svelte", "gotmpl", }, })

will become

return { filetypes = { "html", "css", "sass", "scss", "less", "svelte", "gotmpl", }, }

in lsp/emmet_ls.lua - file name is very important btw
