Unable to serialise CallRecord types

[cowlinb6]

Similar issue to #212 but with CallRecord types.

When attempting to serialise a CallRecord type:

var callRecord = await _graphServiceClient.Communications.CallRecords[id]
    .GetAsync((config) =>
    {
        config.QueryParameters.Expand = new string[] { "sessions($expand=segments)" };
    });
var raw = KiotaJsonSerializer.SerializeAsString<CallRecord>(callRecord);

This fails with the error below:

System.InvalidOperationException: AdditionalData can not be null
   at Microsoft.Graph.Models.Entity.get_AdditionalData()
   at Microsoft.Graph.Models.Entity.Serialize(ISerializationWriter writer)
   at Microsoft.Graph.Models.CallRecords.CallRecord.Serialize(ISerializationWriter writer)
   at Microsoft.Kiota.Serialization.Json.JsonSerializationWriter.WriteObjectValue[T](String key, T value, IParsable[] additionalValuesToMerge)

   at TeamsPbxTest.GraphClient.GetCallRecord(String id) in C:\Users\Ben\source\code\TeamsPbxTest\TeamsPbxTest\GraphClient.cs:line 177

How should I be serialising this type?

Thanks for raising this @cowlinb6

I suspect the error you're seeing is related to microsoft/kiota#4514. However, AdditionalData should be automatically initialized when the object is created in the constructor. Do you still get the error if you add the line below before serializing?

callRecord.AdditionalData = new();

If I add this:

callRecord.AdditionalData = new Dictionary<string, object>();
var raw = KiotaJsonSerializer.SerializeAsString<CallRecord>(callRecord);

Then it fixes the exception but I only get this in the response:

This is probably because of the backingStore. We're looking to enhance the KiotaJsonSerializer to have the option to set the flag for you.

Does the following work for you?

var callRecord = await _graphServiceClient.Communications.CallRecords[id]
    .GetAsync((config) =>
    {
        config.QueryParameters.Expand = new string[] { "sessions($expand=segments)" };
    });
callRecord.BackingStore.InitializationCompleted = false;
var raw = KiotaJsonSerializer.SerializeAsString<CallRecord>(callRecord);

Yes this does work.

Thanks @andrueastman for the quick response on this

Thanks for confirming. We'll close this one for now.
