I can confirm this issue and agreed, issue seems to be around the missing default role.

[SimonGurney]

As a workaround until its fixed, add the extra variable proxy_disable_env=false to the ansible -e

[sshimojo]

@SimonGurney Thanks for fixing!

[SimonGurney]

Thanks @sshimojo but I don't think this should be closed out until the PR is merged. Do you agree?

[sshimojo]

@SimonGurney Sorry, I agree.

[SimonGurney]

This can be closed, fixed by #7729
