title: Google Cloud - does not have storage.buckets.get access to the Google Cloud Storage bucket
body: <p>I have a service account that has Storage Admin role. When I try to use <code>client.lookup_bucket('xyz')</code> I get the following access error:</p>
  <pre><code>google.api_core.exceptions.Forbidden: 403 GET https://storage.googleapis.com/storage/v1/b/xyz?projection=noAcl: &lt;svc_account&gt; does not have storage.buckets.get access to the Google Cloud Storage bucket.
  </code></pre>
  <p><code>xyz</code> is a bucket that does not exist. I am able to access an existing bucket. But according to documentation - lookup_bucket will get a bucket by name, returning None if not found.</p>
  <p>Can anyone tell me why I get the Forbidden error even though I have Storage Admin role (I even tried Owner role for the entire project and I still get the same error)</p>
