The scopes parameter should be passed when creating the OAuth2 badges client. As it is an optional parameter, when it's empty, it will be initilised with the supported scopes for the backpack issuer. It will happen, for instance, when a call is done to oauth2callback.php because, as defined in RFC6749, OAuth2 authorization response only supports code and state.
