Hi Community

We are working on a triggered send logic for Opportunity object. We are doing this in the Salesforce Marketing Cloud connector. 
According to the Marketing Cloud documentation we added the foolowing trigger for Opportunity object.
 

Trig_Opportunity on Opportunity (after insert, after update) 
{ 
    et4ae5.triggerUtility.automate('Object Name'); 
}

Once we added this trigger we are getting the following error when create new opportunity record.
>> Developer script exception : Trig_Opportunity : Trig_Opportunity: execution of BeforeInsert caused by: System.NullPointerException: Attempt to de-reference a null object (et4ae5)

Does anyone know how to fix this issue? 

Thanks in advance.
