[MongoDB의 MotorClient](https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop)를 사용할 때) `RuntimeError: Task attached to a different loop`를 마주친다면, 이벤트 루프가 필요한 객체는 async 함수 안에서만 인스턴스화해야 한다는 점을 기억하세요. 예를 들어 `@app.on_event("startup")` 콜백에서 인스턴스화할 수 있습니다.

如果您在测试程序中集成异步函数调用的时候遇到一个 `RuntimeError: Task attached to a different loop` 的报错（例如，使用 [MongoDB 的 MotorClient](https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop) 时），请记住，只能在异步函数中实例化需要事件循环的对象，例如在 `@app.on_event("startup")` 回调中初始化。

如果在將非同步呼叫整合進測試時遇到 `RuntimeError: Task attached to a different loop`（例如使用 [MongoDB 的 MotorClient](https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop) 時），請記得：需要事件迴圈的物件只應在非同步函式內實例化，例如在 `@app.on_event("startup")` 回呼中。

た際に（例: [MongoDB の MotorClient](https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop) 使用時）、`RuntimeError: Task attached to a different loop` に遭遇した場合は、イベントループを必要とするオブジェクトは非同期関数内でのみインスタンス化するようにしてください。例えば `@app.on_event("startup")` コールバック内で行います。
