title: '500 Backend Error' on Google Fusion Table Insert Table
body: <p>I would like enable a user to create a new Fusion Table through my application.</p>
  
  <pre><code>gapi.client.load('fusiontables', 'v2').then(function() {
    var request = gapi.client.fusiontables.table.insert({
      'columns'      : [{
                        'name': 'test'
                       }],
      'isExportable' : true,
      'name'         : 'Foobar',
    });
    request.then(function(resp) {
      alert(resp)
    }, function(reason) {
      console.log(reason);
      alert('Error: ' + reason.result.error.message);
    });
  });
  </code></pre>
  
  <p>Everything appears to be working fine but my response continues to be status code 500 "Backend Error". </p>
  
  <p>I went to <a href="https://developers.google.com/apis-explorer/#p/fusiontables/v2/fusiontables.table.insert" rel="nofollow">https://developers.google.com/apis-explorer/#p/fusiontables/v2/fusiontables.table.insert</a> and used the API explorer to execute the same. The result there was 500 as well. Does anyone know why this is happening/how I can succeed in creating a new Fusion Table for my users?</p>
