I started seeing an error yesterday when doing this command:

    tempest UPPER_CONSTRAINTS_FILE=https://releases.openstack.org/constraints/upper/master tox -eall -- baremetal --concurrency=1

The specified regex doesn't match with anythingError: InvocationError for command /opt/stack/new/tempest/.tox/tempest/bin/tempest run --regex baremetal --concurrency=1

Any ideas how could I resolve this?

Thanks!
