AWS CFN build is failing with status "Value of property TargetGroupARNs must be of type List of String" for the following autoscalling group:

My target group name is "InfyTG". Only "TargetGroupARNs" was given under autoscaling group for mapping. I also have used the following, but that did not work.
TargetGroupARNs:
Ref: InfyTG
Should be problem mapping targetgroup to autoscaling group. I try searching how the mapping will be between autoscaling group, target group, application load balancer but it didn't helped me fixing the above problem.
All I need is highly available application server under a target group so that I can route the traffic through application load balancer to the instance. If the instance is down, autoscalling group should generate new one and register it under the same target group.
Kindly help me with this.
