In certain cases, issuing an iControl REST or tmsh list rule command on a non-existent iRule can return successfully with an empty list. Instead it should return an error that the specified iRule does not exist.


The user is unable to rely on receiving an error from tmsh or iControl REST if they query for iRules that do not exist.


If any iRule happens to exist in a different folder than the current folder context.


There is no workaround.

Fix Information

Issuing a list command for a non-existent iRule now successfully returns an error.
