Already same option tried but not work

Hi Shahaji,

The OnException handler will only be called when you don't have an exception handler on the screen.

On your screenshot, you already have an exception handler for Communication Exception which is redirecting the user to an error screen, so you have two options there:

• You want to just show a feedback message to the user - keep one of the Feedback Messages you have under the Communication Exception branch and finish in an End node, not with a screen navigation. On the Feedback message, you control the message you want to display to the user.

• You want the user to be redirected to an error screen displaying the error message - Make sure your Error screen can receive an input parameter with the error message and display it on  the screen. Remove the two Feedback Messages and just redirect to the Error screen, passing the message you want as a parameter.
