title: Not authorized to perform cloudformation DescribeStacks despite AdministratorAccess [Serverless, Lambda, IAM]
body: <p>I tried to deploy using the following command.</p>
  <p><code>sls deploy --stage=stage --profile=[my-profile]</code></p>
  <p>And it gives the error.</p>
  <pre><code>Serverless Error ----------------------------------------
   
    User: arn:aws:iam::[my-iam-user] is not authorized to perform: cloudformation:DescribeStacks on resource: arn:aws:cloudformation:ap-northeast-1:[my-lambda-endpoint]/* with an explicit deny
  </code></pre>
  <p>My IAM user has AdministratorAccess policy, so I can't understand why the error occured</p>
