Error: "pasta" is not supported: invalid network mode

what this error really means?
can you open this in the podman project, is not clear what we can do here without having more details about the error

[BenTheElder]

I think this is basically that rootless podman networks don't support "connect".

For all other runtimes, it makes sense to create the registry first then later connect to the cluster network.

For rootless podman you may have to take a different approach.
