[ERROR] Cannot list. substring not found.

What could be the reason? Here is a snapshot of the rally log:

Hello again,

The first issue we need to sort is that you are running python 3.7, this python release is end of life, and we stopped support some time ago. Infact, the last release we made with 3.7 support was 1.4.1 which was in Feb 2020.

If you are on amazon linux 2, then I believe you need to enable their extended library for access to python versions newer than 3.7
