I am temporarily working around the error by updating function Lib:IsUnusable(id) in API.lua to this, but it's unclear what the side effects are:

function Lib:IsUnusable(id)
	if Unfit:IsItemUnusable(id) then
		return true
	elseif Lib.Unusable[id] == nil and IsEquippableItem(id) then
		Lib.Unusable[id] = (function()
			local lines = C.TooltipInfo.GetItemByID(id).lines
			for i = #lines-1, 5, -1 do
				if lines[i].args then
					local class = lines[i].args[2].stringVal:match(L.CLASS_REQUIREMENT)
					if class then
						return not class:find(L.PLAYER_CLASS)
					end
				end
			end
		end)() or false
	end
	return Lib.Unusable[id]
end

I am temporarily working around the error by updating function Lib:IsUnusable(id) in API.lua to this, but it's unclear what the side effects are:

Looks like lines[i].args is always nil, so it will no longer add a red border if your class can't equip the item.
I changed the line to local class = lines[i].leftText:match(L.CLASS_REQUIREMENT) instead and it seems to be working correctly
