I have a sample script which creates EC2, CodeBuild, CodeDeploy and its Deployment Group with ALB and then it goes further to setup with codePipeline, however I am getting an error on CodeDeployDeploymentGroup stage,

Error –
CodeDeployDeploymentGroup
CREATE_FAILED
Likely root cause

The target group name arn:aws:elasticloadbalancing:us-west-2:363010889649:targetgroup/SampleTG/75497adb8b9bc9b8 specified in targetGroupInfoList exceeds the maximum allowed length of 32 characters.

here is the sample script

The sample script is here

what could be the issue? I have tried shorting the names, so I am not sure what could be the problem here.
