title: AWS Credential Helper stopped working after OS update
body: <p>I used to connect to a CodeCommit repo with a Role using the AWS Credential Helper. But after an update ran on my Mac, git started throwing <code>403</code> errors.</p>
  <p>I can verify that the Role that is read by the Credential Helper is being set in the environment variables. I can also see that <code>.aws/config</code> and <code>.aws/credentials</code> are intact. My global <code>.gitconfig</code> is unchanged as well, with the appropriate lines for AWS Credential Helper in there:</p>
  <pre><code>[credential]
      helper = !aws codecommit credential-helper $@
      UseHttpPath = true
  </code></pre>
  <p>I am not sure what else to check. Any ideas as to how to re-connect to the remote would be helpful.</p>
