Hey guys, Any idea why this hasn't been merged?

@SidStraw This change is helpful but it doesnt retain the trace of error, it would be amazing to retain the trace of error after deserialization.

Thank you, this suggestion was very helpful.
This is indeed the part that I did not handle.
I will add this logic.

@SidStraw if this is still needed, it will need to rebased since the code has changed since you originally opened this.

@okuryu thoughts on adding this in?
