make_vcsp_2022.py - vCloud not wanting to sync ISO's

Howdy, I have some ISO's in a folder in the S3 bucket, just called 'ISO' like the blog, and dump the ISO's into there.

When we did so, for some reason vCloud is not wanting to sync the ISO's in some case. Have you experienced this / any workaround?

All VCD is giving us is:

The title identifies make_vcsp_2022.py; start by reading that script and checking how it handles ISO files in the S3 bucket and vCloud synchronization. Reproduce the reported failure if possible using the supplied error trace. Done would require a confirmed cause and a documented workaround or a narrowly specified fix, neither of which the issue currently defines.
