title: Google cloud storage API: unable to open file
body: <p>I am using this piece of code to look at the response status:</p>
  <pre><code>for i, status in enumerate(result.statuses):
          print('Status of processing line {} of the csv: {}'.format(
              i, status))
          # Check the status of reference image
          # `0` is the code for OK in google.rpc.Code.
          if status.code == 0:
              reference_image = result.reference_images[i]
              print(reference_image)
          else:
              print('Status code not OK: {}'.format(status.message))
  </code></pre>
  <p>And, I get this error message:</p>
  <pre><code>Processing operation name: projects/furniture-vs/locations/us-west1/operations/63a6b48c2c4ef9c0
  Processing done.
  Status of processing line 0 of the csv: code: 5
  message: &quot;Error opening file: gs://furniture-vsearch/dtbo160x90x75w5m1-hero-618173ee-high.jpeg.&quot;
  </code></pre>
  <p><em><strong>But we can see that the file is present in the location:</strong></em></p>
