Create contact without company

Hi

Is it possible to create contacts(Person) that has no associated company, through the api? I have set the global setting "Mandatory Company on Contact" to false.

The code below causes Object Reference exception somewhere in superOffice

    public async Task CreatePerson(int personId, string email, string firstName, string lastName)
    {
        var contactAgent = new ContactAgent(_config);
        try
        {
            var person = await contactAgent.AddPersonAsync(0, new PersonEntity()
            {
                Emails = new[] { new EntityElement() { Value = email } },
                Firstname = firstName,
                Lastname = lastName
            });
        }
        catch (Exception e)
        {
            throw;
        }
    }
