I’m getting the following error when trying to test my Apex Test Class
Message:
System.NullPointerException: Attempt to de-reference a null object
Stack Trace error:
Class.RenewalNotificationController.mergeExistingFields: line 321, column 1 Class.RenewalNotificationController.mergeAndCreateMail: line 227, column 1 Class.RenewalNotificationController.sendMail: line 177, column 1 Class.RenewalNotificationControllerTEST.testRenewalNotifications: line 71, column 1
Below is the Apex Test Class
I’ll add my Apex Class shortly.
Any help is greatly appreciated!
Cheers!

The stack trace is telling you where the problem is:
Class.RenewalNotificationController.mergeExistingFields: line 321, column 1.Go to that line and look at the code. Back up from that point and see how you might have gotten a NULL value there. Look at your debug log to see the call path and observe the values of the fields passed to that function. Add additional
System.Debug()statements if necessary.You have everything you need to figure out the problem, and there’s not much SO can do without having access to the code in your Salesforce Org.
