title: Python Apache Beam failed to retrieve information from BigQuery table due to "This app is blocked"
body: <pre><code>import apache_beam as beam
  
  with beam.Pipeline() as p:
  
      table_spec = 'clouddataflow-readonly:samples.weather_stations'
  
      (p | beam.io.ReadFromBigQuery(table=table_spec))
  </code></pre>
  <p>I tried to run the script above to get information from bigquery table, it prompt me to login using my google account and to give access to &quot;apitools&quot;.</p>
