Cannot insert contact without account?

Question

I am trying to test a trigger which works on Account Contact Relationship so I want to perform the following:

• Insert an account
• Insert a contact
• Insert an account contact relationship (my trigger performs some textual extraction to find out account and contact)

My trigger however generates an exception:

System.DmlException: Insert failed. First exception on row 0; first error: INVALID_CROSS_REFERENCE_KEY, You can't associate a private contact with a company.: [ContactId]

This is the code that generates the exception:

    Account account = new Account(Vat_Code__c = 'Examplevat' ,Name = 'Example company2');
    insert(account);
    Contact contact = new Contact(FirstName  = 'John', LastName = 'Smith', Fiscal_Code__c = 'MyFiscalCode1');
    insert(contact);
    Test.startTest();
    AccountContactRelation relation = new AccountContactRelation(SurrogateId__c = 'MyFiscalCode1_Examplevat_Owner');
    insert(relation);
    Test.stopTest();

Is it necessary to have a primary account connected to the company before I could have a secondary connection?

Answer 1

The Contact should be created with the AccountId field populated from the Account that you just created. Once you do that, your problem should disappear. Just change the following line in your code:

Contact contact = new Contact(FirstName  = 'John', LastName = 'Smith', accountId = account.Id, Fiscal_Code__c = 'MyFiscalCode1');
