AssertionError [ERR_ASSERTION]：无效的寄存器选项“value”必须是对象

Question

我正在尝试设置nodeJS应用程序。使用Hapi和PostgreSQL DB。提到所有文件，但错误仍然存在。而server.register

server.register({
  register: require('hapi-node-postgres'),
  options : {
    connectionString: "Postgresdb://dbuser:dbpassword@localhost/dbName"
  }
}, err => {
console.log(err);
});

即将发生的错误是：

UnhandledPromiseRejectionWarning: ***AssertionError [ERR_ASSERTION]: Invalid register options "value" must be an object

请协助。我正在使用“hapi”：“^ 17.5.3”“hapi-node-postgres”：“^ 4.1.0”
