missing %s and %s in section of %s

Error message

missing %s and %s in section of %s

What it means

Configuration guard in OpenstackConfig.getCredentialFromFile: while parsing the clouds.yaml/standard OpenStack config file, the [Default] section is missing one of the mandatory authentication fields (identity auth URL or password). The named value from the parsed section is empty, so gophercloud AuthOptions cannot be built. (The message's double-%s renders the missing key name and section name.)

Solutions

1. Add the missing key (identity or password) to the Default section of the OpenStack config file (e.g. ~/.config/openstack/clouds.yaml or /etc/openstack/clouds.yaml)
2. Verify the config file is valid YAML and the section name matches what the tool expects
