Unable to parse JSON Schema and resolve the reference

I am having one JSON Schema with ref. I am trying to resolve all the ref using JsonSchemaResolver. But, unfortunately , ref is not resolved and getting an error as below.

I am trying to get the substituted JSON by resolving all the ref.

Code:

        var schemaFileContents = File.ReadAllText(schemaFileName);
        JsonSchemaResolver resolver = new JsonSchemaResolver();
        var result = JsonSchema.Parse(schemaFileContents, resolver);
        Console.WriteLine(result);

JSON Schema:

{
  "$schema": "YYYYYYY",
  "id": "XXXXXX",
  "title": "Current Employee Details",
  "description": "XXXXXXXXXXXXX",
  "type": "object",
  "properties": {
    "EMP": {
      "title": "Employee ",
      "description": "Details of the Employee",
      "$ref": "#/definitions/Employee"
    }},
    "definitions": {
      "EmployeeAddress": {
        "title": "Address",
        "description": "EmployeeAddress - Present Address",
        "type": "object",
        "properties": {
          "type": {
            "type": "string",
            "enum": [
              "EmployeeAddress"
            ]
          },
          "address": {
            "title": "Address",
            "type": "string"
          },
          "postalCode": {
            "title": "Postal Code",
            "type": "string"
          }
        },
        "required": [
          "postalCode",
          "address"
        ]
      },

      "Employee": {
        "title": "Party",
        "description": "Employee Details",
        "type": "object",
        "properties": {
          "firstName": {
            "title": "First name",
            "type": "string"
          },
          "address": {
            "title": "Employee Address",
            "$ref": "#/definitions/EmployeeAddress"
          }
        },
        "required": [
          "firstName"
        ]
      }
    }
  }

Error:

It looks like you are using json schema V4 but JsonSchemaResolver expects the json schema V3. The difference between them is in required field. Try to use it on the property level with bool value instead of the array value on the higher level:

"address": {
    "title": "Address",
    "type": "string",
    "required": true
}

According to docs JsonSchemaResolver is obsolete. To use json schema with the latest standards you need to use the separate package. Use the JSchemaPreloadedResolver, see the example here

JsonSchemaResolver is now deprecated. Try below and use Newtonsoft.Json.Schema NuGet

var schemaFileContents = File.ReadAllText(schemaFileName);
JSchemaPreloadedResolver resolver = new JSchemaPreloadedResolver();
var result = JSchema.Parse(schemaFileContents, resolver);
Console.WriteLine(result);
