I'm deploying an application to AWS using the CloudFormation plugin for Azure DevOps.
It works really well, and will automatically update things that need changing, leaving other things alone. I've been working on it for a few days, and it works fine.
However I just saw the following error when committing a small change:
Test for existence of change set Dev-TV-API-ChangeSet-Release-42 returned error: 'Stack [Dev-TV-API-NoAuth] does not exist'.
That looked a bit strange, so I thought maybe it's having trouble working out what needs to change. So I decided to delete the stack manually, and re-run the pipeline. Now I get exactly the same error. The stack shows up in AWS with status REVIEW_IN_PROGRESS - and a single event.
Any ideas what could be going on here?

It turns out that some of the validation which happens before a template is deployed is logged in a different place. So while I was seeing this error in the task log, and nothing much in the AWS Stack Info page, there is a "Change sets" tab at stack level, listing the failed changeset. If you click on that, you will see a status reason describing the error, which should help with debugging.
