getWorldLight() doesn't work

[Capaverde]

it seems to only return the world light color, 215

int32_t LuaScriptInterface::luaGetWorldLight(lua_State* L)
{
	//getWorldLight()
	LightInfo lightInfo;
	g_game.getWorldLightInfo(lightInfo);
	lua_pushnumber(L, lightInfo.level);
	lua_pushnumber(L, lightInfo.color);
	return 1;
}

it seems only the last pushed number is effectively pushed
try
a,b = getWorldLight() and a is 215 and b is nil
the same way, t = {getWorldLight()} gives #t = 1, t = {215}
