title: Firebase Local Emulator and Big-Query: Invalid Table Name
body: <p>I don´t know if this is the right place to ask for help - but maybe someone could give me some tip:</p>
  <p>I am trying to push my data from my project (running in local emulator suite) to big-query. Therefore I copied the extension code from <a href="https://github.com/firebase/extensions/tree/master/firestore-bigquery-export" rel="nofollow noreferrer">'https://github.com/firebase/extensions/tree/master/firestore-bigquery-export'</a></p>
  <p>I added a cloud function to export my members-collection and when I create a new document in that collection, the big-query dataset and table are created, too.
  but i get the following error message in my local console:</p>
  <blockquote>
  <p>&quot;Error when mirroring data to BigQuery ApiError: Invalid table name:
  undefined.firestore_members.members_raw_changelog&quot;</p>
  </blockquote>
  <p>Could anyone give me a hint? is that &quot;undefined&quot; property the projectId? And why isn´t it set? If I do an</p>
  <p><code>console.log('PROJECT-ID:', await this.bq.getProjectId());</code></p>
  <p>in the initialize function it´s displayed correctly...</p>
