Hey, so I'm trying to get goxls to work on neovim, here's what I did:

Procedure

  1. Install goxls using gop install github.com/goplus/goxls@latest
  2. Start the LSP manually when entering *.gop files:
-- Custom LSPs
vim.api.nvim_create_autocmd("BufEnter", {
	pattern = "*.gop",
	callback = function()
		vim.lsp.start({
			name = "goxls",
			cmd = { 
				os.getenv( "HOME" ) .. "/go/bin/goxls",
			},
			root_dir = vim.fn.getcwd(),
		})
	end,
})
  1. When opening a main.gop files, the following error is thrown:
[START][2024-08-31 13:42:11] LSP logging initiated
