Hi,

The below trigger was fired after updating the field twice, but it was not fired before update.
 

trigger age on Account (before update) {

  Map<Id,Account> ageMap = new Map<Id,Account>(); 
  Account[] acct = [SELECT Id,Age__c FROM Account WHERE Id IN : Trigger.newMap.keySet()];
    
     for(Account a : trigger.new){
           

            if(a.age__c != null){
             
                ageMap.get(a.Id);
                a.Is_Age_Updated__c = true;
               
            }
            else{
                
             ageMap.get(a.Id);
             a.Is_Age_Updated__c = false;
            }                  
    }

}

 

I'm unable to deploy my big object due to the error as shown below. I have created the package, but it has thrown the below error.


My zip folder

Hi
I have created an apex trigger to update contact address when the account address is changed. The code worked fine for already created accounts, but when I have created a new account the following error was thrown and I was not able to save the account. Please help me.
