JsonDeserializer fails to convert empty json array into dictionary.

[niemyjski]

C# Code

    public Dictionary<string, object> ExtendedData { get; set; }

Returned JSON Snippet

,
"ExtendedData":{

},

Unable to cast object of type 'RestSharp.JsonArray' to type 'System.Collections.Generic.IDictionary2[System.String,System.Object]'. at RestSharp.Deserializers.JsonDeserializer.CreateAndMap(Type type, Object element) at RestSharp.Deserializers.JsonDeserializer.ConvertValue(Type type, Object value) at RestSharp.Deserializers.JsonDeserializer.Map(Object target, IDictionary2 data)
at RestSharp.Deserializers.JsonDeserializer.Deserialize[T](IRestResponse response)
at RestSharp.RestClient.Deserialize[T](IRestRequest request, IRestResponse raw)

Also as per the change log pertaining to using JSON.NET. The latest nuget release doesn't contain a JsonSerializer on the RestClient (https://github.com/restsharp/RestSharp/blob/86b31f9adf049d7fb821de8279154f41a17b36f7/RestSharp/Serializers/JsonSerializer.cs).

Did you fix this issue or just close it?

I just closed it. Posting issues on Groups reaches a wider audience. You're more likely to get help form there.

GitHub issues are for logging real issues... Google groups is for
discussions and getting help finding the root cause to an issue.. I took
the time and gave you reproduction steps/code...

It would be nice if this was fixed so others don't experience this... But
I've since moved on....

Yep, you're right. Its probably a legitimate issue that shouldn't be dismissed. I'll reopen it. Would be happy to take pull requests for any bug fixes as usual.

This appears to be fixed already. Let me know if you still run into this.

I'm having a similar issue using 104.3.3

Given the following POCO and JSON:

POCO

public class CandidateContainer {
    public Dictionary<string, object> Candidate { get; set; }
}

JSON Response

{
  "candidate": {
    "TEC-DesiredLocation": [],
    "EmploymentType": [
      "Temporary \/ Consulting"
      ],
    "state": "US-CA"
  }
}

I get the following error while attempting to deserialize via the myClient.Execute<CandidateContainer>(myRequest); call

Am I doing something wrong? Everything seems fine until the deserializer hits the JsonArray.

Error occurs in method below

private object CreateAndMap(Type type, object element)
{
    var instance = Activator.CreateInstance(type);

    // Error here: 
    // Unable to cast object of type 'RestSharp.JsonArray' to type         
    // 'System.Collections.Generic.IDictionary`2[System.String,System.Object]'.
    Map(instance, (IDictionary<string, object>)element);

    return instance;
}

I believe your issue is that it doesn't know what type to deserialize to. Your dictionary is <string, object> which is not specific enough. If you have further questions or need support ask on the google groups forum.

I hear what you're saying, but there are a few things that would make thing think, perhaps this should work, i.e.:

• It seems to work no problem with other data types (i.e. the deserializer / JsonObject will infer Int, Bool, etc without a problem and assign them to my dictionary properly typed).
• The XmlDeserializer is very similar to the Json one, particularly in the ConvertType() method, except the XmlDeserializer has an extra else if statement: else if (type.IsSubclassOfRawGeneric(typeof(List<>))) .

I have a minor change that I'll submit a pull request for that solves this issue
