MongoServerError: BSON field 'insert.jsonSchema' is an unknown field

Question

I am new in MongoDB. I want to do client side field level encryption.

Here is the full project link which one I am practicing: https://javascript.plainenglish.io/mongodb-client-side-field-level-encryption-csfle-for-beginners-5eed965d4ba3

Requirments: What I have Installed.

MongoDB Enterprise server 6.0, npm i mongodb-client-encryption uuid-base64 mongodb

I am getting this error when running node app.js app.js

const fs = require("fs");
const mongodb = require("mongodb");
const { MongoClient, Binary } = mongodb;

const base64KeyId = "fFGm1x/fRIWlWPLWhvf1Ig==";
const buffer = Buffer.from(base64KeyId, "base64");
const keyIdBinary = new Binary(buffer, Binary.SUBTYPE_UUID);
const JSONSchemaCreator = require("./schema-creator");

const jsonSchemas = JSONSchemaCreator(keyIdBinary); 

const connectionString = "mongodb://localhost:27017/";

const keyVaultNamespace = "encryption.__keyVault";

const path = "./master-key.txt";
const localMasterKey = fs.readFileSync(path);

const kmsProviders = {
  local: {
    key: localMasterKey,
  },
};

const patientSchema = {
  "medicalRecords.patients": jsonSchemas,
};

const extraOptions = {
  mongocryptdURI: "mongodb://localhost:27020",
};

const secureClient = new MongoClient(connectionString, {
  useNewUrlParser: true,
  useUnifiedTopology: true,
  autoEncryption: {
    keyVaultNamespace,
    kmsProviders,
    schemaMap: patientSchema,
    extraOptions: extraOptions,
  },
});

async function insertPatient(name, bloodType, ssn) {
  try {
    await secureClient.connect();
    const keyDB = secureClient.db("medicalRecords");
    const collection = keyDB.collection("patients");
    const writeResult = await collection.insertOne({
            name,
      ssn,
      bloodType,
    });
    console.log(writeResult);
  } catch (writeError) {
    console.error("writeError occurred:", writeError);
  }
}

insertPatient(
  'Jon Doe',
  "O+",
  '1234567',
);

all of my server connection is perfect. ** error:**

writeError occurred: MongoServerError: BSON field 'insert.jsonSchema' is an unknown field. This command may be meant for a mongocryptd process.

Please help me out and thanks in advance

I have a jsonschema format which one need create and perform encryption push into db

schema-creator.js

module.exports = function (keyId) {
    return {
      bsonType: "object",
      encryptMetadata: {
        keyId,
      },
      properties: {
        bloodType: {
          encrypt: {
            bsonType: "string",
            algorithm: "AEAD_AES_256_CBC_HMAC_SHA_512-Random",
          },
        },
        ssn: {
          encrypt: {
            bsonType: "int",
            algorithm: "AEAD_AES_256_CBC_HMAC_SHA_512-Deterministic",
          },
        },
      },
    };
  };
