Also, I did find this: podman-container-tools/podman#21293
It indicates that an additional parameter might be needed:
--userns=keep-id:uid=xxxxxxxxxx,gid=yyyyybamapookie commentedon Sep 9, 2025
Updated to include that I am using rootless podman.

I added
10000 < a.uid ? `--userns-keep-id:uid${a.uid}=,gid=${a.gid}` : "" ,to the docker command line inmain.js, and that worked.
