How to use defold globals in teal modules?

Questions

I should prefix this by saying that while I’ve done game dev before I haven’t used defold until this week :).

So I have a simple teal module:

local M = {}

-- Define the type of the action argument
local record Action 
	x: number
	y: number
end

-- Function to update hover state on a list of GUI nodes
function M.update_hover(items: { string }, action_id: integer | nil, action: Action): boolean
  print("update havoer")
	if action_id ~= nil then
		return false
	end
	--
	for _, item in ipairs(items) do
		local node = gui.get_node(item)
		if gui.pick_node(node, action.x, action.y) then
			local current_color = gui.get_color(node)
			local yellow = vmath.vector4(1, 1, 0, 1)
			local white = vmath.vector4(1, 1, 1, 1)
			if current_color == yellow then
				gui.set_color(node, white)
			else
				gui.set_color(node, yellow)
			end
		end
	end

	return true
end

return M

To update some highlights on some buttons. When I run tl gen from the command line it all works fine and I end up with the corresponding lua file, but when I try to build from inside defold it complains that gui and vmath are unknown variables.

I’ve tried defined the types in a globals.d.tl and add that in my global_env_def in tlconfig.lua but get the same issue.

Is this because there’s no types defined in defold for teal?

For reference here’s my globals.d.tl:

-- vmath.vector4 type
global record vmath.vector4
   x: number
   y: number
   z: number
   w: number
end

global record vmath
   vector4: function(x: number, y: number, z: number, w: number): vmath.vector4
      return {x = x, y = y, z = z, w = w}
   end

end

-- gui type
global record gui
  get_node: function (name: string): string
  pick_node: function (node: string, x: number, y: number): boolean
  get_color: function (node: string): vmath.vector4
  set_color: function(node: string, color: vmath.vector4): nil
end

Any tips/help appreciated.
