Pcluster create failed after specifying iam role

[yinjun111]

I tried to create a new torque cluster using ParallelCluster using a specific iam role for the new cluster. I was able to create the cluster without specifying "ec2_iam_role = ParallelClusterAdmin" in the config file. But add that, the creation failed. Moreover, I am using the exactly the same iam role in the EC2 instance to create the cluster, e.g. ParallelClusterAdmin

Here is the error message:

pcluster create torque04 -c Config/config.txt
