Hello. If I am overriding some required config variables using ENV Vars, such as secrets.cipher, can I leave it out of my config file? Kratos seems to be trying to validate the config file and telling me the value is missing even though I have specified it as an Env var. Just wondering if my env var is defined incorrectly or if this is expected behavior. Also, is there any way to list the 'active' config using the cli?
