Fargate cli not working

[ssolipuramwex]

Installed the latest version of fargate cli.
./fargate --version
fargate version 0.3.2

I am using IAM instance profile with IAM policies attached to the ec2 instance where fargate cli is installed. When i run the fargate list command it throws an error with elb target groups. I also added ec2 full access permission to the ec2 instance. Still getting the same error:

./fargate service list --region us-west-2 --cluster tomcat
[!] Could not describe ELB target groups
TargetGroupNotFound: One or more target groups not found
status code: 400, request id: b4e96486-eb75-4018-9dc3-8241962ea937

Not sure what the error is related. Can anyone provide any suggestion here?
