Cause


When events are processed, it also looks to map the classification of the event when creating an alert. It looks to classify an alert based on the value from the event. Example: IT, Security.

Classification value is a mandatory field for the alert to be created. If you are mapping the Classification to a null value in the event transform rule, Alert creation will fail with the mentioned exception. 

Resolution


Do not map classification to null in your event transform rule.
