Just spent the last few hours trying to work out why my Pulumi config wasn't working for a project when it is literally a copy paste of a previous project that does work. Turns out this docker image was pulling 2.12.2 of Pulumi, whereas the previous project was on

2.11.2

. Looks like 2.12.x introduced breaking changes AWS around certificate generation and domain validation.

Pulumi SDK versions shouldn’t be tied to how the providers work. Do you mind double checking that the AWS provider dependency version didn’t change?

The issue appears to be with the AWS provider v3.10.0 https://github.com/pulumi/pulumi-aws/issues/1188
