title: elasticsearch field populated with object Object
body: <p>My index defines this column as:</p>
  
  <blockquote>
    <p>:service_data => { :type => 'string', :index => 'no' }</p>
  </blockquote>
  
  <p>and I am populating it with an array of JSONs</p>
  
  <p>In elastic HQ i see the data as: </p>
  
  <blockquote>
    <p>[object Object],[object Object]...</p>
  </blockquote>
  
  <p>What am I doing wrong?</p>
