pgAudit_Analyze - parse error in pgaudit_analyze.log

Hi

I have configured pgAudit extension on my DEV PostgreSQL instance.
I am trying to configure the pgAudit_Analyze to read the audit logs and loads them into a database table.
Following the steps in https://github.com/pgaudit/pgaudit_analyze I have perl script pgaudit_analyze running as a daemon process. I can see csv files in my log directory, however, in the pgaudit_analyze.log I am seeing the following errors consistently.
