title: Google Cloud Functions Deployment Failure - Unexplained
body: <p>We're trying to deploy our Google Cloud Functions, but keep getting this error. We get the same error when trying to trigger our functions.</p>
  
  <p>Everything worked fine until today, with no code changes.</p>
  
  <p><strong>Error message</strong>:</p>
  
  <pre><code>ERROR: (gcloud.beta.functions.deploy) OperationError: code=13, message=Failure in the execution environment
  </code></pre>
  
  <p><strong>Steps Taken</strong>:</p>
  
  <ul>
  <li>Delete all functions </li>
  <li>Redeploy all functions (gcloud SDK)</li>
  </ul>
  
  <p>AFAICT, these are Kubernetes errors, which appears to be a GCF implementation detail leaking through.</p>
