Deserializing OpenAPI "Petstore" sample definition fails

When I try to deserialize the OpenAPI 3.1 Petstore sample definition from Swagger Editor as follows:

YamlSerializer.Deserialize<OpenApiDocument>(openApiDefinitionString);

this fails with the exception System.Text.Json.JsonException: `tokenUrl` is required for oauth flow object

I went ahead and attempted to check whether the spec satisfies the schema using JsonSchema.Net. For this I converted the spec to JSON using Swagger Editor and removed all the irrelevant parts which left me with

{
  "openapi": "3.1.0",
  "info": {
    "title": "Swagger Petstore - OpenAPI 3.1",
    "version": "1.0.11"
  },
  "servers": [
    {
      "url": "https://petstore3.swagger.io/api/v3"
    }
  ],
  "paths": {},
  "components": {
    "schemas": {},
    "securitySchemes": {
      "petstore_auth": {
        "type": "oauth2",
        "flows": {
          "implicit": {
            "authorizationUrl": "https://petstore3.swagger.io/oauth/authorize",
            "scopes": {
              "write:pets": "modify pets in your account",
              "read:pets": "read your pets"
            }
          }
        }
      },
      "api_key": {
        "type": "apiKey",
        "name": "api_key",
        "in": "header"
      }
    }
  }
}

(This still yields the same error in Graeae).

When I validate the spec against the Open API 3.1 schema using JsonSchema.Net:

using System.Text.Json.Nodes;
using Json.Schema;

Json.Schema.OpenApi.Vocabularies.Register();
SchemaRegistry.Global.Register(Json.Schema.OpenApi.MetaSchemas.OpenApiDialect);
SchemaRegistry.Global.Register(Json.Schema.OpenApi.MetaSchemas.DocumentSchema);

var openApiSchema = JsonSchema.FromFile("OpenAPI-3.1-Schema.json");

using var definitionStream = File.OpenRead("petstore.json");
var jsonNode = JsonNode.Parse(definitionStream);
var evaluationResults = openApiSchema.Evaluate(jsonNode);

if (!evaluationResults.IsValid)
{
    Console.WriteLine("Validation Failed!");
}

the validation passes.

I need to use Graeae for the validation as the program needs to be able to validate OpenAPI 3.0 schemas as well and this doesn't work with JsonSchema.Net.
