Data Deployment Error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY: <object> Before: execution of BeforeInsert caused by: System.NullPointerException: Attempt to de-reference a null object

When doing a data deployment, Salesforce may return the following error:

“CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY:SBQQ.ProductRuleBefore: execution of BeforeInsert caused by: System.NullPointerException: Attempt to de-reference a null object” 
 
Salesforce triggers are most likely causing the execution of the insert or update operation to fail. 

To fix this issue, temporarily disable the conflicting triggers, re-deploy your data template and re-enable the triggers.

How did we do?
