    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 Chanchal,

    This is the equivalent of the Null Pointer Exception in Java.

    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.

    Hope this helps.

    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.
