Duplicate entries in a multi reference field are not deserialized properly #356

Closed chamook closed 2 weeks ago

chamook commented 2 weeks ago

I have an entry with a multi reference field that might contain duplicate entries. Newer versions of the library return null for the repeated entries instead of the expected object.

I saw this issue and can get it to work as expected by using 8.0.1

This is my first time working with Contentful, so by all means tell me that I'm holding it wrong if that's the case 😅 but I think the regression between versions hints at it being a real issue and not just me

Test Code:

public sealed record Divider(string Direction);
public sealed record TestPage(IReadOnlyList<dynamic> Components);
public sealed class TestController(
    ILogger<TestController> Logger,
    IContentfulClient ContentfulClient)
    : Controller
{
    [HttpGet("/test-contentful")]
    public async Task<IActionResult> Test()
    {
        Logger.LogInformation("Testing contentful...");
        var results =
            await ContentfulClient.GetEntries<TestPage>(
                queryString: "?content_type=staticPage&fields.slug=test-page&include=2");

        foreach(var result in results)
        {
            foreach(var component in result.Components)
            {
                if(component.sys.contentType.sys.id == "divider")
                {
                    string direction = component.ToObject<Divider>().Direction;
                    Logger.LogInformation("Direction: {direction}", direction);
                }
            }
        }

        return NoContent();
    }
}

@chamook Thanks for the detailed issue! I'll have a look and see if I can figure out what's going wrong here.

Roblinde commented 2 weeks ago

@chamook just looking at the test-classes I see you're using this has some weird issues where json.net turns it into a JObject which can't be used to actually deserialize into a strong type or resolve references. If you use a strong type with strongly typed properties do you run into the same issue?

chamook commented 2 weeks ago

Changing TestPage to:

public sealed record TestPage(IReadOnlyList<Divider> Components);

and adjusting the test code to work with that can get all the items successfully on 8.3.0:

Is there a preferred way of dealing with references to heterogenous content types that isn't using dynamic? Because that would be great 😀

Roblinde commented 2 weeks ago

Ah great, yeah the dynamics has been a headache unfortunately. However if you have a scenario where you get a number of different content types returned in a single request and want to turn them all into their respective type you need to use a ContentTypeResolver. Here's an example that should still be reasonably up to date: https://www.contentful.com/developers/docs/net/tutorials/using-net-cda-sdk/#get-entries-of-multiple-types-or-by-interface

Hope this helps!

Thank you very much for your help!
