title: Weird issue: Bigquery dataset not found
body: <p>One of our BQ datasets is no longer accessible via BQ Web UI and Cloud Shell. </p>
  
  <p>It shows message "Not found: Dataset project:dataset" immediately upon opening the UI.</p>
  
  <p>We tried a couple of bq shell commands as well:</p>
  
  <ul>
  <li>bq ls: successfully lists the "missing" dataset</li>
  <li>bq ls dataset: returns "BigQuery error in ls operation: Not found: Dataset project:dataset"</li>
  </ul>
  
  <p>But we were able to query the views inside and access the contents of the dataset via PowerBI.</p>
