SDK NullPointerException due to missing @odata.type field during select query

Bắt đầu với User.createFromDiscriminatorValue trong src/main/java/com/microsoft/graph/generated/models/User.java và lần theo JsonParseNode.getChildNode đối với trường @odata.type bị thiếu. Tái hiện vấn đề bằng truy vấn select hoặc đoạn mã JsonNode được cung cấp, sau đó xác minh rằng những người dùng chỉ chứa id, name và mail được ánh xạ và trả về mà không xảy ra NullPointerException.

Describe the bug

During a select query for users, mapping them to the User class fails with following NPE

java.lang.NullPointerException: parameter node cannot be null
	at java.util.Objects.requireNonNull(Objects.java:246)
	at io.kiota.serialization.json.JsonParseNode.<init>(JsonParseNode.java:38)
	at io.kiota.serialization.json.JsonParseNodeFactory.createJsonParseNode(JsonParseNodeFactory.java:32)

	at com.microsoft.graph.groups.item.members.graphuser.GraphUserRequestBuilder.get(GraphUserRequestBuilder.java:70)

Expected behavior

The user(s) should be selected by the query, mapped and returned in a response object

How to reproduce

Code snippet to reproduce:

final String groupId = "test group id";
final GraphUserRequestBuilder request = client.groups()
                .byGroupId(groupId)
                .members()
                .graphUser()
                .get(req -> {
                    req.queryParameters.select = "id,name,mail";
                    req.queryParameters.filter = "id in (1,2,3)";
                    req.queryParameters.count = true;
                    req.headers.add("ConsistencyLevel", "eventual");
                    }
                })

Code snippet to reproduce the NPE with the JsonNode

import com.fasterxml.jackson.databind.node.JsonNodeFactory;
import com.fasterxml.jackson.databind.node.ObjectNode;
import io.kiota.serialization.json.JsonParseNode;
import io.kiota.serialization.json.JsonParseNodeFactory;

class Scratch {
    static void main() {
        try {
            var a = new JsonParseNode(new JsonParseNodeFactory(), new ObjectNode(new JsonNodeFactory(false)));
            var b = a.getChildNode("@odata.type");
        } catch (NullPointerException e) {
            System.out.println("Exception!");
        }
    }
}

Replicating this code in Graph UI returns following example response:

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users(id,name,mail)",
    "@odata.count": 2,
    "value": [
        {
            "id": "id 1",
            "name": "name 1",
            "mail": "mail 1"
        },
        {
            "id": "id 2",
            "name": "name 2",
            "mail": "mail 2"
        }
    ]
}

Which then leads to the NPE as the SDK is expecting @odata.type field being set here

https://github.com/microsoftgraph/msgraph-sdk-java/blob/main/src/main/java/com/microsoft/graph/generated/models/User.java

@jakarta.annotation.Nonnull
    public static User createFromDiscriminatorValue(@jakarta.annotation.Nonnull final ParseNode parseNode) {
        Objects.requireNonNull(parseNode);
        final ParseNode mappingValueNode = parseNode.getChildNode("@odata.type"); <- NPE being caused here
        if (mappingValueNode != null) {
            final String mappingValue = mappingValueNode.getStringValue();
            switch (mappingValue) {
                case "#microsoft.graph.agentUser": return new AgentUser();
            }
        }
        return new User();
    }
