Package lookup fails with error in 'affects'

[tunloop]

Debian 11
Python 3.9.2
NVD CVE 1.1 Json DBs

In order to get downloads to work, I had to change CVE 1.0 to CVE 1.1. Not sure if that is the cause of the following problem.
When running test check against 2 packages, lookup fails with "KeyError: 'affects'"

# python3 cvechecker.py
