Technical Note: CSTN 00008 - Playbook 'Update Record' stores Null value for a field post removing the value

Issue: 

When we use Playbook --> Update Record --> and add value to “Assigned Date” of Alerts and save it. 

Later when we remove the value for “Assigned Date” and add values for a couple of other fields, it is noticed that “Assigned Date” value is null.

 Due to which the Playbook fails. 

Root cause:

Whenever the value is removed from the assigned field, it stores the empty string and which is getting passed during execution and causing the playbook to fail.

Fix:

    There is both short-term and permanent fix for the issue.

Short-Term Fix:

Have to remove the step and reload again to get it working

Permanent Fix: 

4.11 and above has this issue resolved.
