Strange behaviour of OSC in keystone MFA context

Hello, I'm experiencing the following strange behavior of openstack CLI with os-auth-methods option (most parameters are defined in clouds.yaml): $ openstack token issue --os-auth-type v3multifactor --os-auth-methods password,totp The plugin p could not be found Note that "p" is the first letter of "password". It looks like the option parser handled "password,totp" as a string instead of as a list of strings. Version of openstack CLI is 5.4.0. Any idea ? Thanks ! Jean-François
