title: How to set a variable to 'null' in a Azure Logic App?
body: <p>I need to send null under a certain if case to a CRM Endpoint.</p>
  
  <p>Since I need the value on multiple parts of the Logic App I would like to use a variable.</p>
  
  <p>This code only set the variable to "" but not to null.
  I need the null in the case when the IC_CODE is not '05'.</p>
