I'm writing code(trigger) that checks the dbd_id field in an Account. The field should not be null or empty. If you try to convert a lead with an empty dbd_id field, you will get an error message. You must fill it in the Lead first. I want to change an error message on the lead conversion page to "Please fill your "DBD ID"" using the addError() method in the accountHandler.apxc class, but it does not work. I don't know whether it's about the condition in the code or not. Please help me.
Here is the error I want to change( to "Please fill your DBD ID") on the conversion page:
There was an error converting the lead. Please resolve the following error and try again: AccountTrigger: execution of BeforeInsert caused by: System.NullPointerException: Attempt to de-reference a null object Class.AccountHandler.CheckDBD: line 61, column 1 Class.AccountTriggerHandler.beforeInsert: line 10, column 1 Class.TriggerDispatcher.Run: line 18, column 1 Trigger.AccountTrigger: line 13, column 1
