2021-07-13 16:22:36,703 WARNING [oslo_policy.policy] JSON formatted policy_file support is deprecated since Victoria release. You need to use YAML format which will be default in future. You can use ``oslopolicy-convert-json-to-yaml`` tool to convert existing JSON-formatted policy file to YAML-formatted in backward compatible way: https://docs.openstack.org/oslo.policy/latest/cli/oslopolicy-convert-json-to-yaml.html.
