Mongodb client isConnected property is deprecated

[JinYuSha0]

see https://github.com/mongodb/node-mongodb-native/commit/5a37a9244aa8a3ca0ce137c42f6593d99aca98ee

and then will throw error: Casbin mongo adapter not connected

if (this.mongoClient.isConnected === undefined) {
  throw new Error('Casbin mongo adapter not connected');
}

That's how I solved it for now

async function loadEnforcer() {
  const model = path.resolve(__dirname, "../config/rbac_model.conf");

  const adapter = await MongoAdapter.newAdapter({
    uri: process.env.DATABASE_URL,
    option: {
      useNewUrlParser: true,
    },
    database: process.env.DATABASE_NAME,
    collection: "casbin",
  });

  await adapter.mongoClient.connect();

  const e = new Enforcer();

  await e.initWithAdapter(model, adapter, true);

  adapter.mongoClient.isConnected = true;

  await e.loadPolicy();

  return e;
}
