Need HELP : Character consistency workflow using Mick Mumpitz JSON files on Comfyui cloud base

[PoseCameraClick]

Hi! Has anyone had any luck running the JSON character consistency workflow file on the Comfyui Cloud base. I've tried so many times and I keep getting errors. I'm a new to GitHub and I know nothing about coding - I'm a creative looking to understand the workflow so that i can integrate it into my creative process. Has anyone come across a similar workflow that's easier to understand? Thanks in advance. I also work on a Mac book Pro
