do until where the until is a json property

[Robin Southgate]

Hi,

I'd like to do something like the following:

- name: Wait for Security Group to be applied
  command: "aws rds describe-db-instances --db-instance-identifier {{ target_db_environment }}-mysql-db-{{ current_time }} --output json"
  register: db_info
  set_fact:  
    security_group_json: "{{ db_info | from_json }}"
    security_group: "{{ security_group_json.DBInstances[0].VpcSecurityGroups[0].VpcSecurityGroupId }}"
    security_group_active: "{{ security_group_json.DBInstances[0].VpcSecurityGroups[0].Status }}"
  until: "{{ security_group }} == 'sg-XXXXXXXX' && {{ security_group_active }} == 'Active'"
  retries: 5
  delay: 5

But I can't mix the set_fact in there like that. Is there any way, within the register two properties of the returned json? Otherwise is my only option a regex in the until that looks for both the security group and the Status=Active?
