Cant go past sky replacement error dialog

[s1esset]

Running a script that starts a simple action, sky replacement on current image, flatten, thats it. Then through python im saving the image and closing the doc so next image can start processing same action.

But when no sky is found i get a error that i cant go past,

a error popup dialogue stops the script from continuing that says "could not complete the sky replacement command because of a program error"

How can i "press the ok and move on" or just suppress the dialog box?
