title: Parsing Error while uploading CSV files to AWS Neptune
body: <p>I want to solve Parsing Error occurring in uploading CSV files to AWS Neptune.</p>
  
  <p>The problem may be occurred by column name and its type, but I do not know what types are right to write in the header.</p>
  
  <p>I transformed types of all the data as string before uploading CSVs.</p>
  
  <p>Problem does not occur:"~id","pv_time:String","order_num:String","staff_num:String","~label"</p>
  
  <p>Ploblem occurs:"order_num","order_from:String","order_to:String","station_name:String","~label"</p>
