title: Calling iot:attachPolicy from AWS Lambda
body: <p>I'm trying to attach a policy from a AWS Lambda and I'm getting 403 with the following error:</p>
  
  <p>'User: arn:aws:sts::acc-nbr:assumed-role/XXX/XXX is not authorized to perform: iot:AttachPolicy on resource: XXXX'.</p>
  
  <p>I've added 'IotFullAccess' to the role selected in the lambda but the issue is still there. Any  suggestions? </p>
  
  <p>Thanks!</p>
