IAM SDK AmazonIdentityManagement; Status Code: 404; Error Code: NoSuchEntity; - amazon-web-services

Question

AmazonIdentityManagementClient identityManagementClient = new AmazonIdentityManagementClient();
System.out.println("This is the role");
GetRoleResult roleResult = identityManagementClient.getRole(new GetRoleRequest().withRoleName("myRole"));
System.out.println(roleResult.getRole().toString());
System.out.println("This is the Policy");
GetRolePolicyResult rolePolicyResult = identityManagementClient.getRolePolicy(new GetRolePolicyRequest()
.withRoleName("myRole").withPolicyName("AmazonS3FullAccess"));
System.out.println(rolePolicyResult.getPolicyDocument());
System.out.println(rolePolicyResult.getPolicyName());
I have attached IAM role to my instance - myRole. I have attached it AmazonS3FullAccess policy to myRole. The above code I am using to fetch the policies associated with myRole using SDK but I am facing NoSuchEntity Exception when I try to fetch Policy. I am able to get Role name and my output is myRole but I am facing error when I try to fetch Policy details.
I don't know why.
What I am doing wrong here?

Answer 1

I only managed to get the policy document in an alternative way (AWS Java SDK v.1x) - by using getPolicyVersion method of the AmazonIdentityManagementClient.
The GetPolicyVersionRequest for this is for the policyArn (which you can get from the policy details of the listAttachedRolePolicies result for your role name) and the versionId is from calling the getDefaultVersionId() on the policy returned by the AmazonIdentityManagementClient 's getPolicy for your policyArn.
