S3TransferManager-Sample | IAM getList policy issues

I am having this error in my getList call:

S3TransferManagerSample[1717:48308] listObjects failed: [Error Domain=com.amazonaws.AWSS3ErrorDomain Code=1 "The operation couldn’t be completed. (com.amazonaws.AWSS3ErrorDomain error 1.)" UserInfo=0x7fb71412d300 {HostId=qhjcOyYAPQjHhJIX5REMTN5A48ecxIkHCqt6fFwkQPBff+tKWnML9A4yQobq2C38, Message=Access Denied, Code=AccessDenied, RequestId=B6920900AB17C864}]
