[Bug]: Unable to add HTTPS listeners for Backend Service after the Private Load Balancer is created

Description:

Unable to add HTTPS listeners for Backend Service after the Private Load Balancer is created. Getting error below.

CustomResource attribute error: Vendor response doesn't contain InternalHTTPSListenerArn attribute in object arn:aws:cloudformation:ap-southeast-1:<redacted>

I created this Internal ALB first with only HTTP listeners while testing, without HTTPS listeners in mind to configure them later. After adding certificate field in environment manifest and http.alias in Backend Service manifest, i am getting error above.

Details:

Copilot version: v1.33.1
OS: macOS 15
Manifest: Backend Service
AWS Region: ap-southeast-1

Observed result:

When running copilot svc deploy, am getting error above that cannot find HTTPS listener ARN. The HTTPS listener was created at the internal LB after running copilot env deploy but running copilot svc deploy for the http.alias, error above pops up.

Expected result:

Expecting to able to simply add another HTTPS listener.

Debugging:

I have to delete the LB and redeploy again.
