errors during upgrade automation preflight VNA

Products

• Network Observability
• Virtual Network Assurance

Issue/Introduction

we are upgrading from 24.2.9 to 24.3.12 using upgrade automation.

I generally re-use the inventory.remote, ansible.cfg and variables.yml so there is the possibility new variables were introduced in 24.3.12

I am getting the following preflight errors

Result: Netops VNA
-----------------------------------------------------------------------------
Failure (/tmp/netopsInstall/vnaAnsiblePreflightOutput.txt)
AnsibleUndefinedVariable: 'vna_ui_username' is undefined. 'vna_ui_username' is undefined

Environment

DX NetOps :: All Supported Versions

VNA :: All Supported Versions

Cause

This variable was added both to the VNA install/upgrade and the UA upgrade in 24.3.11
