Python Script Modification -- 2

I am looking for a skilled Python developer who can help me with modifying my existing Python script. The main focus of the project is to fix existing bugs and ensure that the script is working correctly.

Using:
https://github.com/ecarat237/zabbix_ipsec_pfsense
Script : zabbix-ipsec.py

Error:
Traceback (most recent call last):
File "/usr/local/bin/zabbix-ipsec.py", line 80, in <module>
ret = getPayload()
^^^^^^^^^^^^
File "/usr/local/bin/zabbix-ipsec.py", line 61, in getPayload
data = parseConf().items()
^^^^^^^^^^^
File "/usr/local/bin/zabbix-ipsec.py", line 40, in parseConf
m3 = m3.group(0)
^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'group'
