Enumerable type not in the response

For a given enumerable property:

public virtual IList<string> QuestionsAndAnswers { get; set; }

when calling Content Delivery API:

/api/episerver/v3.0/content/5421?expand=*

All properties of the block are received except the `QuestionsAndAnswers`.

Using:
- EPiServer.CMS 12.15.1
- EPiServer.CMS.Core 12.11.0
- EPiServer.ContentDeliveryApi.Cms 3.6.0

How should I let the API return that list?

I believe you need to create your own convertor see here for an example

Property Lists Serialization and Content Delivery API (optimizely.com)

Thank you!

Basing on your post, I was able to figure out the solution for IEnumerable<string>:

public class ListPropertyConvertorProvider : IPropertyConverterProvider
{
    private readonly IServiceProvider _serviceProvider;

    public ListPropertyConvertorProvider(IServiceProvider serviceProvider)
    {
        _serviceProvider = serviceProvider ?? throw new ArgumentNullException(nameof(serviceProvider));
    }

    public IPropertyConverter? Resolve(PropertyData propertyData)
    {
        return propertyData switch
        {
            StringListProperty => _serviceProvider.GetRequiredService<StringItemListPropertyConverter>(),
            _ => null
        };
    }

    public int SortOrder => 100;
}

public class StringItemListPropertyConverter : IPropertyConverter
{
    public IPropertyModel Convert(PropertyData propertyData, ConverterContext contentMappingContext)
    {
        return new StringItemPropertyModel((StringListProperty)propertyData);
    }
}

public class StringItemPropertyModel : PropertyModel<IEnumerable<string>, PropertyList<string>>
{
    public StringItemPropertyModel(StringListProperty type) : base(type) => 
        Value = type.List;
}
