JavaScript to change the Gradient color
Hi,
I have this script that works perfectly fine. However, I have a new requirement to specifically target the gradient layers "Gradient Fill 1456" and "Gradient Fill 1459" within the designated layer groups. Additionally, the left Stop Color of these gradients should match the gradientColorInput color provided by the user.

Layer group name 1: Additional gradients (FOLDER opacity must not exceed 40%)
Gradient Layer name 1: Gradient Fill 1456
Layer group name 2: Crop Gradient (Don't use with other graident)
Gradient Layer name 2: Gradient Fill 1459
In the Gradient Layer 1 and 2, there's a gradient fill applied. The left Stop Color value in the gradient map should match the 'gradientColorInput' color (user Input as per the script).
