Seeking Help with Batch Processing PSD Wall Art Mockups

Question

My goal is to batch process multiple PSD wall art mockups, replacing the smart objects within each mockup with several image files.

I modified someone’s script for my wall art mockup. My aims to automate this process by iterating through a list of image files and replacing the smart objects in the mockups accordingly. However, despite my efforts, I have encountered difficulties in getting the script to work as intended.

One specific issue I've encountered is the image doesnt resize fit within the picture frame, it enlarges smart object file. I have verified that the file paths are correct and the image files exist at the specified locations. Despite my troubleshooting attempts, I have been unable to resolve this error.

Furthermore, I would like to know if it is possible to utilize multiple PSD wall art mockups in the batch processing script or if I need to restrict it to a single mockup. I am unsure if there are any limitations or specific considerations when handling multiple mockups in a batch process.

I would greatly appreciate any guidance, insights, or suggestions you could provide to help me troubleshoot and resolve the issues I am facing. Additionally, if there are any best practices or recommended approaches for batch processing PSD mockups with smart object replacements, I would be grateful to learn about them.
