Unknown type 'setmetatable' type error. Why?

[ww_waylon09]

--!strict

type Map = {
	Name : string;
	Icon : string;
}
type MapSlot = {
	__index : MapSlot;
	new : (Map) -> setmetatable<{}, {__index : typeof(MapSlot)}>;
}

local mapSlot = {} :: MapSlot
mapSlot.__index = mapSlot

function mapSlot.new(map : Map)
	return setmetatable({}, mapSlot)
end

Warning occurs on line 9:

What am I doing wrong?

Using the same code, I don’t have the warning pop up (instead, it highlights MapSlot as an unknown).
Just to check - if you go to File → Beta Features, then look for New Luau Type Solver, is it enabled? If not, can you please try enabling it?

Someone turned off Workspace.UseNewLuauTypeSolver in the team create place…

Anyway, thanks for bringing the new type solver to my attention. I didn’t realize setmetatable<> doesn’t work with the older type solver.
