Error while connecting to Quickbooks

[mmrasheed]

Hi, I am new to ERPNext. I have successfully installed and configured the latest version. However, I am stuck at connecting to Quickbooks using the master branch. I am receiving the following error while trying to connect to Quickbooks-

Traceback (most recent call last):

Any idea on how to solve this issue? I appreciate your help.
