Auth0 Deploy CLI error

Problem statement

During a deployment using the Auth0 Deploy CLI, we got the error message
Additional properties not allowed: new_universal_login_experience_enabled' on property flags


This new_universal_login_experience_enabled flag had previously been deprecated. And its removal should have no impact on your tenant. The sudden onset of this error in the CLI was due to a recent update in your environment to the Auth0 Management API (which is leveraged by the Deploy CLI), which removed this flag.
