de-reference a null object

Hello Chanchal,

This error is caused by a line of code that is trying to use an object that has not been instantiated, or an object’s attribute that has not been initialized.

NOTE: If the field Site was left empty, it will generate the error message as well.

Thanks.

Hi,

Mostly this error occurs when you have not initialize the list/set/map etc and using their methods.

When you query any sobject with no records and then using its fields somewhere in code without null or empty check

Hope this helps.
