array<int> intArray = {42, 1337};

ContainerSerializationSaveContext writer();
JsonSaveContainer jsonContainer = new JsonSaveContainer();
jsonContainer.SetMaxDecimalPlaces(5);
writer.SetContainer(jsonContainer);
writer.WriteValue("", intArrayArray);
auto res = jsonContainer.ExportToString();
Print(res);If I let him write array<array<int>> instead of array<ref array<int>> as you "normally" do it crashes with an access violation. I have my reason why the data array itself does not keep the reference. The inner array is held alive somewhere else to make my API more convenient to use.
