❔ Serialization Posting Issues

I am having an issue where my Model has a virtual collection in it, however when creating a new entry it is failing because it is expecting that collection which is not present. Model

public class CustomerDTO
    {
        public Guid Id { get; set; } 
        [Required]
        public string Name { get; set; }
        public bool IsTestCustomer { get; set; } 
        public virtual ICollection<CustomerClientDTO> CustomerClients { get; set; }
    }

public class CustomerDTO
    {
        public Guid Id { get; set; } 
        [Required]
        public string Name { get; set; }
        public bool IsTestCustomer { get; set; } 
        public virtual ICollection<CustomerClientDTO> CustomerClients { get; set; }
    }

Service

            var settings = new JsonSerializerSettings
            {
                NullValueHandling = NullValueHandling.Ignore
                MissingMemberHandling = MissingMemberHandling.Ignore
            };
            var content = JsonConvert.SerializeObject(customer,settings);
            var bodyContent = new StringContent(content, Encoding.UTF8, "application/json");
            var response = await _httpClient.PostAsync("api/customer", bodyContent);
 
        }

            var settings = new JsonSerializerSettings
            {
                NullValueHandling = NullValueHandling.Ignore
                MissingMemberHandling = MissingMemberHandling.Ignore
            };
            var content = JsonConvert.SerializeObject(customer,settings);
            var bodyContent = new StringContent(content, Encoding.UTF8, "application/json");
            var response = await _httpClient.PostAsync("api/customer", bodyContent);
 
        }

Now it is failing because the Controller is expecting

{
  "id": "3fa85f64-5717-4562-b3fc-2c963f66afb6",
  "name": "ass",
  "isTestCustomer": true,
  "customerClients": []
}

{
  "id": "3fa85f64-5717-4562-b3fc-2c963f66afb6",
  "name": "ass",
  "isTestCustomer": true,
  "customerClients": []
}

but it is only getting

{
  "id": "3fa85f64-5717-4562-b3fc-2c963f66afb6",
  "name": "ass",
  "isTestCustomer": true
}

{
  "id": "3fa85f64-5717-4562-b3fc-2c963f66afb6",
  "name": "ass",
  "isTestCustomer": true
}

I cant seem to find a google result for this

NM. I got it needed to nullable the collection.

public virtual ICollection<CustomerClientDTO> CustomerClients { get; set; }

public virtual ICollection<CustomerClientDTO> CustomerClients { get; set; }

and change to

public virtual ICollection<CustomerClientDTO>? CustomerClients { get; set; }

public virtual ICollection<CustomerClientDTO>? CustomerClients { get; set; }

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
