Python 3.8 error in cloudify while running ansible

Question

I am trying to run the blueprint Ansible-Azure-VPC which is in the marketplace of Cloudify. I am getting the following error: : [DEPRECATION WARNING]: Ansible will require Python 3.8 or newer on the controller starting with Ansible 2.12. Current version: 3.6.8 (default, Nov 16:: 2020, 16:55:22) [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]. This feature will be removed from ansible-core in version 2.12. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg. : /opt/manager/resources/deployments/default_tenant/923cbe8d-c30e-4c13-95de-cd1260dda2b6/tmpb2n01dut/lib/python3.6/site-packages/ansible/parsing/vault/init.py:44: CryptographyDeprecationWarning: Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography. The next release of cryptography will remove support for Python 3.6.

Following is my cloudify.yaml
