Expected Behavior

Not sure, it should just override existing service account or something but not fail.

Current Behavior

It fails, if I delete the service account manually and then deploy. Then it works.

Reproduction Steps

It doesn’t happen the first time your create the cluster since there is no service account. But anytime it has to update the service account it fails.

Possible Solution

Would you be able to share us detailed step by step procedure you are following to get to this error. We recommend to start with one of our sample patterns such as generic-cluster-construct and multi-team-construct and try to update the AwsLoadBalancerControllerAddOn addon and let us know when you are facing this issue so that we can try to recreate. Most important part is having able to recreate the issue. We can fix the issue once we recreate it.
