-------------------------------------------
Thanks for reporting the issue [~archanat].
I think message was truncated to avoid excessive logging. But true there should

For simplicity I am thinking to make the truncate length configurable and don't
truncate by default . [~arpitagarwal], do you have any other view on this?
