This error occurs when Photoshop cannot find enough visible pixels to make a selection. This can happen in a few situations listed below.

• If the action requires brushes for it to work, please ensure your brush opacity is set to 100% before playing the action.
• You have brushed over your photo with a very faint brush. Please use a brush with 100% opacity when brushing onto your ‘brush’ layer.
• You have only brushed a very small area or very thin lines. Most of my actions use the area within the area that you brush to create effects out of – so it is important you create a large enough brushed area to avoid Photoshop running into selection errors.
• In some rare cases, the resolution of your document might be set to something very small like 20. Ensure your document is set to 72dpi or greater before playing the action.
