Notion.Net throws JsonSerializationException when retrieving block children - c#

I need to retrieve children from a notion block (page). I use C# with Notion.Net library. There's a database, with other pages at rows. I'm trying to retrieve such page's children with
await notion.Blocks.RetrieveChildrenAsync(id);
It causes an exception:
Newtonsoft.Json.JsonSerializationException: Could not create an instance of type Notion.Client.IBlock. Type is an interface or abstract class and cannot be instantiated. Path 'object', line 1, position 68129.

I already used other notion library with python. Even now It successfully retrieves block children with the same Id. I don't know, how to solve It(
I expected to get all page block children. It seems, that some serialization errors occured. I can't find difference between cases.

Json Net $ref without id

I want to use $ref to point to an attribute rather than an id in an object.
Specifically, in the below example, I want AlternateAdress to point to city attribute in Address1
String str3 = "{
'Name': 'Jon Smith',
'Address1': { '$id': '1', 'City': 'New York', 'State': 'NY'},
'AlternateAddress':{'$ref':'#/Address1/City'}}";
Person stuff = JsonConvert.DeserializeObject<Person>(str3, settings);
Console.WriteLine(stuff.AlternateAddress);
The above code returns an error

I have referenced this project in azure functions and also I can see this dll in Azure function's bin. But I still get this error. Any insights on this issue would be helpful.

ElasticSearch or Fsharp crashing with this error

I'm trying to read data from a node with elastic search but I'm getting this error whenever I try to. Is anyone familiar with this problem? The times when it passes, the response result is empty and contains no data. Have been trying to many possible ways and none of them seem to work, and this method has always been working until now.

NEST 5.x Dependency on NEST 2.x?

I'm currently using NEST 5.0.0-rc3, but haven't been able to get any queries to run.
For example, this query:
var client = new Nest.ElasticClient(connectionSettings);
var searchResponse = client.Search<Page>(s => s
.MatchAll()
.From(0)
.Size(10)
.Source(f => f.Includes(i => i.Field(x => x.Id)))
);
Generates the following .net exception (sorry formatting is kind of rough):
<Error>
<Message>An error has occurred.</Message>

Do/should I need to pull in a reference to the 2.x version of nest as well?

There is no dependency on NEST 2.x by NEST 5.x; this sounds like you have something else compiled against/referencing NEST 2.x which should also be referencing/compiled against 5.x.

JsonConvert.DeserializeObject, Index was outside the bounds of the array

All of this is origianlly from https://github.com/JamesNK/Newtonsoft.Json/issues/469
Posted here because I first looked on SO and didn't see anything, so I posted on the project's GitHub page.
We're currently using JsonConvert.SerializeObject and JsonConvert.DeserializeObject<T> to send data between a client and server.
I created a tool that creates 10 clients, sends a command to 10 different servers, the servers serialize a response and send it back over the network, then the 10 clients deserialize the object on the local machine.
I'm running these 10 tasks concurrently in the thread pool, and about 20% of the time all of the JsonConvert.DeserializeObject calls fail with the following stack trace:
Error: Index was outside the bounds of the array.

at MyClientCode()
MyClientCode() is using DeserializeObject like this:
string json = GetServerResponse();
return JsonConvert.DeserializeObject<ResponseObject>(json);
The ResponseObject is pretty big, and includes several composite objects. However, I can save the json and deserialize it properly with DeserializeObject, so I don't think the object structure is the problem.
Doing some research of the List error indicates that this occurs when trying to modify a List object concurrently.

From James Newton-King:
A new JsonSerializerInternalReader is created each time you
deserialize an object. Each deserialization happens in its own state.
A high volume server that it deserializing incoming JSON will be
deserializing many many things at the same time without issue.
My guess is you have multiple deserializers working over the same
list.
Thanks James. After digging deeper I found that you're right, we were using the same list object for multiple instances of the deserialized type. Specifically, the object looked something like this:
class Obj {
static List<string> _validSelections = new List<string>() { "One", "Two", "Three", "Four" };
public IEnumerable<string> ValidSelections { get { return _validSelections; } }
... more ...
}
The exception was being thrown on line 1261 of JsonSerializerInternalReader.cs when trying to add objects to the list concurrently.
After seeing how this is implemented in our code, I am going to get rid of the static backing since it wasn't providing us anything anyway.
