Script that iterates through the layers and applies a Color Overlay style to each one.

[Rodrigo21788888pltm]

Photoshop version:

26.0.0

Error: 

Error 8800: General Photoshop error occurred. This functionality may not be available in this version of Photoshop.

- The command “Set” is not currently available.

Line: 60

->      executeAction(charIDToTypeID("setd"), desc, DialogModes.NO);

What am I doing wrong when I execute the action? (sorry the comments are in Spanish)

I looked at the code, but I couldn't debug the error. Can you post screenshots of the two required layer style's values/settings?
