What exception does Security.stripInaccessible throw?

Question

This new security method Security.stripInaccessible both strips out fields that the user has no rights to and will throw an exception if the object-level permissions are being violated.

What exception type is thrown (so I can catch and handle that specific type)?

Answer 1

It's a System.NoAccessException. The message is:

No access to entity: MyObject__c

Not sure the easiest way to verify, but I set up a Visualforce Page with the below controller so the running user didn't need appropriate permissions to execute anonymous Apex.

public with sharing class Demo
{
    public String type { get; private set; }
    public String message { get; private set; }
    public Demo()
    {
        try
        {
            Security.stripInaccessible(AccessType.CREATABLE, new List<NoPerm__c> {
                new NoPerm__c()
            });
        }
        catch (Exception e)
        {
            message = e.getMessage();
            type = e.getTypeName();
        }
    }
}

And the markup was simply:

<apex:page controller="Demo">
    <apex:pageMessage severity="FATAL"
                      summary="{!type}"
                      detail="{!message}" />
</apex:page>
