CloudFormation stack CREATE_FAILED because of "Internal Error"

Hey folks,

I was trying to replicate the service I work on to a separate burner account. I was able to replicate all the other stacks except the ECS Service stack (the main one for the service). I get an error while running bb cdk deploy <ECSServiceStackName> which says:

Received response status [FAILED] from custom resource. Message returned: Internal Error (RequestId: f67e9cec-b153-47fa-8bf6-8c1ac962394c)

I believe it is due to other resources that failed to create:

The following resource(s) failed to create: [LoadBalancerBE9EEC3A, LambdaCanary44B53221, SslCertificateArnSsmParameterFBC7F579]. Rollback requested by user.

Based on the events and time stamps I can see that the SslCertificateArnSsmParameter resource failed first (also started creating first) due to which the other 2 are failing. Is this Certificate resource an issue with regards to a burner account? Is it okay that I am trying to replicate this resource in a separate AWS account apart from the original Alpha account (Yes, I am replicating all the resources from the alpha account)?

If anyone is curious about why I am replicating everything to a burner account- The goal is to get the service up and running in a separate AWS account and for that I am trying it on a burner account first before going ahead with a new permanent Conduit account.

TIA :)
