Hai,

For a requirement, I want to customize the processor.py handle\_message method. Can anybody tell me how to override the OOB processor.py?

If you want to customize it, you can fork the project and change whatever you’d like. As to specifcally what to do, that will depend on what you are trying to accomplish. What do you want to change?

Which exception? It’s possible there’s another solution to the problem you’re facing. Can you explain it in more detail please? An example of the situation you’re trying to handle would be great too.

I want to send a message to the customer when there is an exception while run action. So, I am trying to customize processor.py and catch the exception in the run action method.
