Hi all,

I have a problem with this challenge : 

Write an Apex trigger that fires before records are inserted and ensures that the ShippingState field has the same value as the BillingState field.
Create an Apex class named AccountTriggerHandler that contains a public static method called CreateAccounts to accept the List of Account objects.
For each Account record, before saving, ensure that the ShippingState field has the same value as the BillingState field.
Write an Apex trigger named AccountTrigger that fires before records are inserted.
The Apex trigger must call the AccountTriggerHandler.CreateAccounts() method with the collection of new records.
Create a test class named AccountTriggerTest that inserts 200 Account records with a BillingState of CA. After the insert, test to ensure that all 200 records have a ShippingState of CA.
Before verifying this challenge, run your test class at least once using the Developer Console Run All feature.

and this is my classes :
 

public class AccountTriggerHandler {
    
    public static void CreateAccounts(List<Account> acclist){
        
        
        for(Account a:acclist){
            
            if(a.ShippingState!=a.BillingState){
                a.BillingState=a.ShippingState;
              
            }
        }
    }

}

 

trigger AccountTrigger on Account (before insert) 
{
    if (Trigger.isBefore && Trigger.isInsert) {
			AccountTriggerHandler.CreateAccounts(Trigger.new);
		}	
	}

 

@isTest
public class AccountTriggerTest {
    
    @isTest static void TestCreate200Records(){
        
        // Test Setup data
        // Create 200 new Accounts
        List<Account> accts = new List<Account>();
        for(Integer i=0; i < 200; i++) {
            Account acct = new Account(Name='Test Account ' + i, BillingState = 'CA');
            accts.add(acct);
        
            Test.startTest();
            //insert acct;
        	Test.stopTest();
            
            for (Account a:accts){
                
                System.assertEquals('CA', a.ShippingState, 'ERROR');
            }
            
    }

        
}
}

And this error :
Challenge Not yet complete... here's what's wrong: 
The 'AccountTrigger' Trigger does not appear to be working correctly. Inserted records did not have matching BillingState and ShippingState values.
Anyone can help me please??
Thanks!
 

I am getting error message while solving this challenge in Trailhead :

To complete this challenge, add a validation rule which will block the insertion of a contact if the contact is related to an account and has a mailing postal code (which has the API Name MailingPostalCode) different from the account's shipping postal code (which has the API Name ShippingPostalCode).Name the validation rule 'Contact must be in Account ZIP Code'.
A contact with a MailingPostalCode that has an account and does not match the associated Account ShippingPostalCode should return with a validation error and not be inserted.
The validation rule should ONLY apply to contact records with an associated account. Contact records with no associated parent account can be added with any MailingPostalCode value. (Hint: you can use the ISBLANK function for this check)

Error Message is :  There was an unhandled exception. Please reference ID: HKIZNLVZ. Error: Trailhead::TrailheadTimeOut. Message: Trailhead.view: failed to get a 200 response. Made 3 attempts each resulting in a 403 or 500 failure for url challenges?key=%5B%22trailhead.challenge.validation_rules.en.us.192%22%5D.

I am not sure what went wrong here.
My Validation Rule is on Contact Object  :

  AND ( NOT(ISBLANK( Account.Name)),
( MailingPostalCode <> Account.ShippingPostalCode))

Can anyone please help with this.
