Autoscaling Groups Support more than a single Target

[sd3z]

aws-cdk/packages/@aws-cdk/aws-autoscaling/lib/auto-scaling-group.ts

Line 561 in cbe735e

throw new Error('Cannot add AutoScalingGroup to 2nd Target Group');

I'm not sure if I've implemented this correctly, but I have five Code Deploy applications using 5 different Target Groups that I would like to attach to a single AutoScaling Group

When I attempt to attach a second ApplicationTargetGroup to the same asg it fails with the error Cannot add AutoScalingGroup to 2nd Target Group, but if I jump into the console I can attach multiple Targets.

appWebTargetGroup = new ApplicationTargetGroup(this, 'WebTargetGroup', {}); 
appAPITargetGroup = new ApplicationTargetGroup(this, 'ApiTargetGroup', {}); 

this.asg.attachToApplicationTargetGroup(appWebTargetGroup );
this.asg.attachToApplicationTargetGroup(appAPITargetGroup );

If I was to comment out the line attaching the appAPITargetGroup, everything works as expected.

Actually it looks like this is a bug and the work around was mentioned here
