"Your Apex code contains field level access checks that are redundant now that you've added 'WITH SECURITY_ENFORCED'. Please check your code again."

Code is:-

@RestResource(urlMapping='/secureApexRest')
global with sharing class SecureApexRest {
    @HttpGet
    global static Contact doGet(){
        Id recordId = RestContext.request.params.get('id');
        Contact result;
        if (recordId == null){
            throw new FunctionalException('Id parameter is required');
        }
        if (Schema.SObjectType.Contact.isAccessible()
            && Schema.SObjectType.Contact.fields.Name.isAccessible()
            && Schema.SObjectType.Contact.fields.Secret_Key__c.isAccessible()){
            List<Contact> results = [SELECT id FROM Contact WHERE Id = :recordId WITH SECURITY_ENFORCED];
            if (!results.isEmpty()) {
                result = results[0];
            }
        } else{
            throw new SecurityException('You don\'t have access to all contact fields required to use this API');
        }
        return result;
    }
    public class FunctionalException extends Exception{}
    public class SecurityException extends Exception{}
}

Kindly suggest me what exactly I need to change in the code.
Thanks inadvance.

Hello,

I have complete both requirements of PD 2 certificate, MCQ and Trailhead Badges. I have also linked my Webassessor account with trailhead account. It has been almost one week and I am still waiting for my certificate. I have raised mutiple cases for this but no response. My questions are :

1) Is it common for certificate to arrive late or is it just my case, please let me if anyone of you faced similar situation.
2) Is there any way to reach certificate team apart from guided help on the website.

Also any guess why does it take so long to award this certificate, once you have completed all the requirements. For example in case of proctored exam the certificate is awarded immediately. 

Best Regards,
Rahul

Hi All

I am planning to appear for Salesforce Certified Platform Developer I. Not really getting any sample questions or mock questions online.

Appreciate if anybody has any pointers to that!

Thanks In Advance
