ContainerRegistry::Path::InvalidRegistryPathError: ContainerRegistry::Path::InvalidRegistryPathError

Possible Workarounds

1. Rename project to not have a _ in the project name.
2. For groups or usernames, delete or transfer all projects, then rename the namespace.

Limitations

There is nothing we can do about supporting leading or trailing underscores in container repository paths. Repository paths must conform to the [a-z0-9]+([._-][a-z0-9]+)*(/[a-z0-9]+([._-][a-z0-9]+)*)* regexp defined upstream in the OCI Distribution specification (link).

Proposal

Prevent project's from being created with a leading underscore to ensure this error does not occur.
