Jets 5.0.2 cannot deploy when project completely empty

[feliperaul]

My Environment

Software	Version
Operating System	macOs 12.4
Jets	5.0.2
Ruby	3.2.2

---

Expected Behaviour

Following the Getting Started API example, without even creating any migration (so no database needed), before invoking the scaffold for the first time, it should deploy.

So, basically:

jets new demo --mode=api
jets deploy

Should deploy, but it fails.

Current Behavior

The deploy fails 100% of the time with the following errors:

The Jets application failed to deploy. Jets creates a few CloudFormation stacks to deploy your application.
The logs above show the CloudFormation parent stack events and points to the stack with the error.
Please go to the CloudFormation console and look for the specific stack with the error.
The specific child stack usually shows more detailed information and can be used to resolve the issue.
Example of checking the CloudFormation console: https://rubyonjets.com/docs/debugging/cloudformation/
