title: User not authorised to perform action in AWS Systems Manager
body: <p>I am new to the AWS platform and am trying to do a project similar to what is described here: <a href="https://aws.amazon.com/blogs/machine-learning/build-a-serverless-twitter-reader-using-aws-fargate/" rel="nofollow noreferrer">https://aws.amazon.com/blogs/machine-learning/build-a-serverless-twitter-reader-using-aws-fargate/</a></p>
  
  <p>I am currently in Step 4:Store configuration information in AWS Systems Manager Parameter Store. 
  When I go to Parameter Store in AWS System Manager I get an error saying:</p>
  
  <blockquote>
    <p>User:
    arn:aws:sts::413511889088:assumed-role/vocstartsoft/user292978=pdas@connect.ust.hk
    is not authorized to perform: resource-groups:ListGroups on resource:
    arn:aws:resource-groups:us-east-1:413511889088:/groups-list with an
    explicit deny</p>
  </blockquote>
  
  <p>There is nothing else that displays here except the error. I am using an AWS educate account to do this. Any advice would be helpful.</p>
