Fixing pipeline issues from initial PR

[novekm]

Hi @artur-bolt, I moved this to a new PR as I was working to fix the pipeline errors. One was a minor one around Terraform docs that I pushed a fix for. The other failure is a functional test failure due to using a null in a for expression:

Error: �[0m�[0m�[1mIteration over null value�[0m

Can you look into this and resolve?
