Speaking for
@stocky-spoon-28903 - I expect this was in pulumi-aws, where he has two open PRs:
https://github.com/pulumi/pulumi-aws/pull/254.
The failures in CI are fixed with
https://github.com/pulumi/pulumi-aws/pull/256.
However, CI runs from forks will still not be able to run our full AWS integration tests in our AWS account unfortunately, as doing so would require exposing our AWS account credentials to the forks. So we'll get some validation, but not all.
