Hi all, I have a rule to throw a message when there is an error. I want to prevent send the email if the origin of the error is the API to send the email This is my rule ![](/sites/default/files/inline/images/images/imagen(218).png) Now, If there is any error in any process, it works, but if there is an error in MyProduct.BO.SendEmail it is trying to send the error again, and it is a infinite loop. Is there any way to check what is the origin and don't process if the origin is MyProduct.BO.SendEmail? I've tried to set a condition in when node but it doesn't catch any property of Ens.AlertRequest ![](/sites/default/files/inline/images/images/imagen(219).png) It doesn't work. I'm sure I'm not using the command correctly, so I'm asking for help. What is the correct way to throw the message but not for MyProduct.BO.SendEmail?   Best regads, Kurro Lopez
