Hi,

I am trying to modify one of my test methods to make sure that it complies with some validation rules I recently created.  I also added a lookup filter on the Decision_Maker__c field (lookup on the Contact) so users can only look up Contact that are related to Account that Opportunity is related to.  So if Account A had two contacts, if I create an Opportunity and want to add the Decision Maker field, I only want to be able to find the two contact that Account A has in the lookup filter.  Here's my logic for the filter:

Decision Maker: Account ID equals Field Opportunity: Account ID (required filter)

This is the error that I am getting:

System.DmlException: Insert failed. First exception on row 0; first error: FIELD_FILTER_VALIDATION_EXCEPTION, Value does not exist or does not match filter criteria.: [Decision_Maker__c]

I'm confused because I am pretty sure the Contact that I create in the Unit Test is related the Account I create.  Then the Opportunity I create is related to the Account, so I'm confused on why it's tripping up the error since I related everything together on the original Account.

public static testMethod void TestCreateActualsAndTargets_Trigger(){
    
        Account l_oAccount = new Account(Name='TestAccount', Type='Eligible');
        insert l_oAccount;
        
        User testUser = TestFactory.buildTestASUser(0, 'Standard User');
        insert testUser;
        
        Contact testContact = new Contact ();
        testContact.FirstName='Testo';
        testContact.LastName='Westo';
        testContact.Account=l_oAccount;
        insert testContact;
        
        Opportunity l_oOpportunity = new Opportunity();
        l_oOpportunity.Name='Test Opportunity';
        l_oOpportunity.Type = 'New Ad Sales';
