Management asked for opportunities to be automatically created for accounts with annual revenue greater than $1,000$. A developer created the following trigger on the Account object to satisfy this requirement.
for (Account a: Trigger.new) {
if (a.AnnualRevenue > 1000000) {
List < Opportunity > oppList = [SELECT Id FROM Opportunity WHERE accountId = :a.Id]; if(oppList.size() == 0) { Opportunity oppty = new Opportunity{Name = a.name, StageName = ' Prospecting ' , CloseDate = system.today().addDays(30)}; insert oppty;
}
}
}
Users are able to update the account records via the UI and can see an opportunity created for high annual revenue account. However, when the administrator tries to upload a list of 179 accounts using Data Loader, it fails with System.Exception errors.
Which two actions should the developer take to fix the code segment shown above?
