[aws-eks] Values passed to AddHelmChart are not getting applied

I am trying to apply the Helm chart for “aws-load-balancer-controller” from this EKS charts repository https://github.com/aws/eks-charts/tree/master/stable/aws-load-balancer-controller

I am following the documentation from https://www.eksworkshop.com/beginner/180_fargate/prerequisites-for-alb/ and trying to setup the same via CDK. I have created an iamserviceaccount “aws-load-balancer-controller-test” and i am passing this service account to the chart values like below to my Fargate cluster. But when the cluster comes up, the installation has not taken my service account and instead it is creating a new service account irrespective of the data i passed for values.

cluster.AddHelmChart("albHelm", new HelmChartOptions 
            {
                Namespace = "kube-system",
                Repository = "https://aws.github.io/eks-charts",
                Chart = "aws-load-balancer-controller",
                Release = "aws-load-balancer-controller",
                Values = new Dictionary<string, object> {
                    ["clusterName"] = cluster.ClusterName,
                    ["serviceAccount.create"] = false,
                    ["serviceAccount.name"] = "aws-load-balancer-controller-test",
                },
                Wait = true,
                Timeout = Duration.Minutes(15)
            });

Environment

• CDK CLI Version: 1.73.0
• Node.js Version: v14.15.0
• OS: Windows 10
• Language (Version): C#

I was having the same problem (in typscript). It turned out the values should be passed as an object:

cluster.addHelmChart('AWS LoabBalancer Controller', {
  repository: 'https://aws.github.io/eks-charts',
  chart: 'aws-load-balancer-controller',
  namespace: 'kube-system',
  values: {
    clusterName: cluster.clusterName,
    serviceAccount: {
      create: false,
      name: lbControllerSa.serviceAccountName
    }
  }
});
