Failed To deploy the control plane.

Hi,
I tried to deploy an infrastructure using your playbook (on one zone). I got this issue:

fatal: [localhost]: FAILED! => {
    "msg": "The task includes an option with an undefined variable. The error was: list object has no element 1\n\nThe error appears to be in '/home/deployer/openshift4-ansible/install-upi.yaml': line 193, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n    - name: Create UPI Node Launch (EC2 master instances)\n      ^ here\n"
}

Thanks

this issue is related with use of one zone.
