下面是代码中断的地方：

at /mnt/c/Users/*********/node_modules/knex/lib/transaction.js:191:41

at Function.transaction (/mnt/c/Users/*********/node_modules/knex/lib/util/make-knex.js:75:21)

const writeOrdersToDB$ = (order: Order): Observable<Order> => {
  const orderToInsert = cleanOrder(order);
  return Observable.fromPromise(knex.transaction((trx: Transaction) => trx('order')
    .insert(orderToInsert)
    .returning('*')));
};

const writeOrdersToDB$=（顺序：顺序）：可观察=>{
const orderToInsert=cleanOrder（订单）；
返回可观察的.fromPromise（knex.transaction（（trx:transaction）=>trx（'order'））
.插入（orderToInsert）
。返回（“*”）；
};

无法复制，请添加完整的代码进行测试。可能您的可观察代码没有做您认为它做的事情，并且正在泄漏连接。您能够解决这个问题吗？
