TelescopePreviewerLoaded Error executing vim.schedule lua callback #12

When actions-preview.nvim is installed and the user calls require("actions-preview").code_actions(), it triggers TelescopePreviewerLoaded autocmd, but with a nil args.data.bufname. This causes an error when args.data.bufname is parsed.

Error message:

Error executing vim.schedule lua callback: ...scope.nvim/lua/telescope/previewers/buffer_previewer.lua:460: User Autocommands for "TelescopePreviewerLoaded": Vim(append):Error executing lua callback: .../share/nvim/lazy/ltex-utils.nvim/lua/ltex-utils/init.lua:66: attempt to index field 'bufname' (a nil value)

Fixed in PR #3.

I am having the same issue. The pull request supplied didn't quite fix the issue either. So far what seems to be working for me is

 	vim.api.nvim_create_autocmd("User", {
 		pattern = "TelescopePreviewerLoaded",
 		callback = function(args)
 			---@type string
+			if args.data == nil then
+				return
+			end
 			local extension = args.data.bufname:match("%.(%w+)$")
 			if extension == "md" or extension == "tex" then
 				vim.wo.number = Config.rule_ui.previewer_line_number
 				vim.wo.wrap = Config.rule_ui.previewer_wrap
 			end
 		end,
 	})

In that case, we probably should do:

if args.data == nil or args.data.bufname == nil then
	return
end

This PR also adds a check for args.data being nil:
