EF - Cannot insert the value NULL into column 'Id'
I have this entity: 
public class Address
{
    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int Id { get; init; }

    public required string AddressLine1 { get; init; }
    
    public string? AddressLine2 { get; init; }
    
    public string? AddressLine3 { get; init; }

    public string? AddressLine4 { get; init; }
    
}

public class RiskAddress : Address;

public class CorrespondenceAddress : Address;
public class Address
{
    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int Id { get; init; }

    public required string AddressLine1 { get; init; }
    
    public string? AddressLine2 { get; init; }
    
    public string? AddressLine3 { get; init; }

    public string? AddressLine4 { get; init; }
    
}

public class RiskAddress : Address;

public class CorrespondenceAddress : Address;
I try to autofixture excluding the id but i dont think that works because its int so it will always default to 0 ? - fact check me pls but the db should be handling generating its id, why do i get this error running the following test ? 
[Fact]
    public async Task CanSaveEntityAsyncManual()
    {
        var policy2 = await SetupPolicyHybrid();
        await _dbContext.Policies.AddAsync(policy2);
        await _dbContext.SaveChangesAsync();

        List<Policy> savedPolicies = await _dbContext.Policies.ToListAsync();

        Assert.Equal(1, savedPolicies.Count);
    }
