I tried to deploy a kubernetes cluster with one master node and one worker node in openstack magnum. But it returned an error:

ResourceInError: resources.kube_masters.resources0.resources.kube-master: Went to status ERROR due to "Message: Exceeded maximum number of retries. Exceeded max scheduling attempts 3 for instance c477d0d3-6176-4cec-b5aa-3a2fb7c77435. Last exception: Argument must be bytes or unicode, got 'NoneType', Code: 500"

Additional info:\ Image used: Fedora-CoreOS 32\ Flavor: 4VCPUs, 4GB RAM, 25GB disk\ docker storage driver: devicemapper\ docker volume size: 10GB
