❔ How to deserialize correctly

public record ProductInformation 
{
  public ProductDetails Product {get; init;} // Warnings: Non-nullable property Product is unitialized & auto-property accessor is never user


public record ProductDetails 
{
  public Product {get; init;} // Warnings: Non-nullable property Product is unitialized & auto-property accessor is never user
  public init OwnerId {get; init;} //auto-property accessor is never user
}

[
  {
    "product": {
      "ownerId": "39",
      "product": "1_4873jm_jd"
  }
]

var responseString = await response.Content.ReadAsStringAsync().ConfigureAwait(false); 
if (string.IsNullOrEmpty(responseString))
  return null;
var products = JsonSerializer.Deserialize<IReadOnlyCollection<ProductInformation>>(responseString)
