How to use the typescript-rest.Server function in typescript-rest

constructor() {
        this.server = null;
        this.PORT = parseInt(process.env.PORT, 0) || 3600;

        });
        const db = mongoose.connection;
        autoIncrement.initialize(db);
        db.on('error', (err) => {
            throw new Error('unable to connect to database at ' + config.db + err);
        });
        typescript_rest_1.Server.buildServices(this.app, ...controllers_1.default);
        // TODO: enable for Swagger generation error
        // Server.loadServices(this.app, 'controllers/*', __dirname);
        typescript_rest_1.Server.swagger(this.app, './dist/swagger.json', '/api-docs', 'localhost:3600', ['http']);
        this.app.use((err, req, res, next) => {
            if (res.headersSent) {
