Images of Fence Installations in Adobe Photoshop via JavaScript

Images of Fence Installations in Adobe Photoshop via JavaScript, I have a complicated issue that I need assistance with. I already have the JavaScript code ready, but I'm looking for help to identify the reasons it doesn't function as intended. This program is meant to incorporate fence images into pictures of houses using Photoshop. I've attached a sample house photo for reference. I aim to automate the placement of the fence in these images so that it appears natural within the house photo.

I am working with the extendScript toolkit CC to achieve this. If you can resolve the script issues, I can share all the necessary files with you. I want to specify the fence's placement using coordinates while ensuring it doesn't overlap with the driveway of the house. Each house has approximately nine images, and I will need to adjust the fence's position for every nine batches of photos. Keep in mind that there are at least 3,000 different styles of fence sections, so I would like to automate this process as much as possible.
