I am taking the course in Portswigger.net for SQLi and am stuck in Lab 12 where I cant seem to get the administrator password. I am using this https://github.com/rkhal101/Web-Security-Academy-Series/blob/main/sql-injection/lab-12/sqli-lab-12.py python script to get the password since I am only using burp community edition and I keep getting proxy errors. Here is the error am getting:

`python3 sqli-lab-12.py “https://0aaf00f503f92c0181a707140080003c.web-security-academy.net/”
