Ajay Yadava commented on FALCON-1156:
-------------------------------------
I think this still needs to be addressed as it causes a lot of confusion for
users as is evident in FALCON-75 & FALCON-911. The delete operation can be
successful even when the entity doesn't exist to ensure idempotent behaviour
but the message can be modified to inform the user that the entity didn't
exist.
> Misleading error message while deleting entity which does not exist
