Updating CheckItem.State causes Exception

[JAYDEV-DE]

Hello,

first of all: Thank you for providing this project, it saved me a lot of time so far.

The issue appears after setting the CheckItem.State to "CheckItemState.Complete".

Here the Exception details:

I'm using a brand new clone of this repository.

Error-Class: "Manatee.Trello.ManateeJson.GeneralExtensions" Error-Function: "public static void Serialize(this T obj, JsonObject json, JsonSerializer serializer, string key, bool force = false)"

Error-Details:"System.ArgumentException occurred HResult=0x80070057 Message=Type provided must be an Enum. Parameter name: enumType Source=mscorlib StackTrace: at System.RuntimeType.GetEnumValues() at System.Enum.GetValues(Type enumType) at Manatee.Json.Serialization.Internal.Serializers.EnumNameSerializer._EnsureDescriptions[T]() at Manatee.Json.Serialization.Internal.Serializers.EnumNameSerializer.Serialize[T](T obj, JsonSerializer serializer) at Manatee.Json.Serialization.Internal.Serializers.DefaultValueSerializer.Serialize[T](T obj, JsonSerializer serializer) at Manatee.Json.Serialization.Internal.Serializers.SchemaValidator.Serialize[T](T obj, JsonSerializer serializer) at Manatee.Json.Serialization.JsonSerializer.Serialize[T](T obj) at Manatee.Trello.ManateeJson.GeneralExtensions.Serialize[T](T obj, JsonObject json, JsonSerializer serializer, String key, Boolean force) in C:\Users\Jansen\Documents\Development\TrelloConnector\Manatee.Trello-master\Manatee.Trello.ManateeJson\GeneralExtensions.cs:line 26 at Manatee.Trello.ManateeJson.Entities.ManateeCheckItem.ToJson(JsonSerializer serializer) in C:\Users\Jansen\Documents\Development\TrelloConnector\Manatee.Trello-master\Manatee.Trello.ManateeJson\Entities\ManateeCheckItem.cs:line 29 at Manatee.Json.Serialization.Internal.Serializers.JsonSerializableSerializer.Serialize[T](T obj, JsonSerializer serializer) at Manatee.Json.Serialization.Internal.Serializers.ReferencingSerializer.Serialize[T](T obj, JsonSerializer serializer) at Manatee.Json.Serialization.Internal.Serializers.DefaultValueSerializer.Serialize[T](T obj, JsonSerializer serializer) at Manatee.Json.Serialization.Internal.Serializers.SchemaValidator.Serialize[T](T obj, JsonSerializer serializer) at Manatee.Json.Serialization.JsonSerializer.Serialize[T](T obj)"

It can be reproduced with the following lines of code:

` var serializer = new ManateeSerializer(); TrelloConfiguration.Serializer = serializer; TrelloConfiguration.Deserializer = serializer; TrelloConfiguration.JsonFactory = new ManateeFactory(); TrelloConfiguration.RestClientProvider = new WebApiClientProvider(); TrelloAuthorization.Default.AppKey = ""; TrelloAuthorization.Default.UserToken = "";

        Member MainUser = new Member("<MemberID>");

        Board myBoard = MainUser.Boards.FirstOrDefault();
        Card myCard = myBoard.Cards.FirstOrDefault();
        CheckList myChecklist = myCard.CheckLists.Add("Demo");
        CheckItem myItem = myChecklist.CheckItems.Add("To be 100 %");
        myItem.State = CheckItemState.Complete;

`

Hope someone can help me fixing this problem.

Thanks

Julian

Thanks for reporting the issue. I'll look into it tonight.

Looks like this is actually an issue with Manatee.Json trying to serialize a nullable enum. I'll create an issue over there.

@JAYDEV-DE please download Manatee.Json v9.6.1 (available on Nuget soon). This should resolve the problem.

@gregsdennis Awesome, that was really quick, i appreciate that.

I tested the code snipped, all works fine now - thanks :-)
