Hi Chanti,

Are you sure the list has elements in it?

I suggest you check for the query result, and return null if the list is empty, and the list if the list is not null

Hope it helps

HI Chanti,

As you mentioned System.currentPageReference().getParameters().get('id'); this line meaning is you have to pass any account id in the browser url where you are facing an issue like below.

To get the ID open any account and copy the account ID form the browser URL and paste accordingly like in the below image your issue will get resolved.

Hello Chanti,

You can use below code: 
public class mydbController {

  List<Account> accList = new List<Account>();
  public Account getAccount() {
  
	accList = [SELECT id, name,(SELECT id, firstname, lastname FROM Contacts limit 5) FROM Account where id =:System.currentPageReference().getParameters().get('id')];
	
	if(accList.size() > 0){
		return accList;
	}
	else{
		return null;
	}	
  }
}

-Thanks,
TK

HI Chanti.

If the query retun no records you will get that error.
So you should add  list.size(). Even If query returns empty records. You wont get that error again. If you add list.size().
public class mydbController {
    list<Account> accList=new list<account>();
  public list<Account> getAccount() {
    accList=[select id, name,
 
            (select id, firstname, lastname
             from Contacts limit 5)
            from Account where id =
             :System.currentPageReference()
             .getParameters().get('id')];
   if(accList.size()>0)
   {
    return accList;
       
   }
      else 
      {
          return null;
      }

  }}
