A user receives the generic "An internal server error has occurred" while interacting with a custom Lightning Component.
What should the developer do to ensure a more meaningful message?

global with sharing class MyRemoter {
public String accountName { get; set; }
public static Account account { get; set; }
public AccountRemoter() {}
@RemoteAction
global static Account getAccount(String accountName) {
account = [SELECT Id, Name, NumberOfEmployees
FROM Account WHERE Name = :accountName];
return account;
}
}
Consider the Apex class above that defines a RemoteAction used on a Visualforce search page.
Which code snippet will assert that the remote action returned the correct Account?
Account a = controller.getAccount('TestAccount');
