Windows 10. PS version 24.6. I've been running a script successfully in an action but it suddenly stopped working yesterday, throwing up the illustrated error. The script is designed to change the scale of an embedded object. As I said, it's been working fine for over a year but yesterday started throwing up the error for no apparent reason.
Any help, advice would be most gratefully received.
Could you please post screenshots with the pertinent Panels (Toolbar, Layers, Actions with the fully expanded Action, Options Bar, …) visible?
The error is clearly layer related, but your layer panel isn't visible when the error appears – so we can't see why or really comment.
Perhaps this link may help?
Please do post a screenshot with the layers panel visible when running the script using the same image that failed in your previous screenshot (I'm guessing that there is no layer named "Line 1").
