title: Big Query exports
body: <p>I am trying to export some data from Big Query.
  This is done by first saving the table and then exporting it to google cloud storage.
  This used to work just fine but recently apparently some tables have nested schemas so exporting as csv does not work anymore. Exporting as a JSON should work, and the export job claims to succeed, but data is not available on google cloud storage.
  Anyone experiencing similar issues? Is Google having some problems?</p>
  
  <p>Thanks!</p>
