title: Salesforce bulk API: How to set a date to null
body: <p>I am writing some python code to set some dates to null. According to the documentation, anything that needs to be set to null, will have to contain #N/A on the csv its picking up the data from. However this does not seem to work for date fields. I get the following error:</p>
  
  <p>SalesforceMalformedRequest: Malformed request <a href="https://na131.salesforce.com/services/async/38.0/job/7504O00000LKUpIQAX/batch/7514O00000SWAzPQAX/result" rel="nofollow noreferrer">https://na131.salesforce.com/services/async/38.0/job/7504O00000LKUpIQAX/batch/7514O00000SWAzPQAX/result</a>. Response content: {'exceptionCode': 'InvalidBatch', 'exceptionMessage': 'Records not processed'}</p>
  
  <p>I made sure the field shows up as nillable on workbench as well.</p>
  
  <p>How can I set an existing date to null? Any help is appreciated</p>
