Ps Automate issue

I am facing an issue while launching PS_Automate through CMD.

Initially, there was no issue when I tested it with the default BIWebApp.ini file. However, after making a copy of the same file and renaming it to WAF.ini, I started receiving the following error when trying to launch PS_Automate:

Error: Subscript used on non-accessible variable.

My BeyondInsight/Password Safe version is 26.2.

Could anyone please guide me on what might be causing this issue and how I can troubleshoot or resolve it?
