当我等待很长时间时，如何在 setTimeout 中调用 HttpException？

Question

我从不同的服务器获取产品，我想要 return 异常，等待很长时间。我为此创建了 setTimeout，但它停止了服务器并且没有 return 错误。

如何解决？

      const server = 23;

      const productsTimeout = setTimeout(() => { throw new HttpException('Problem', HttpStatus.INTERNAL_SERVER_ERROR) }, 3000);

      products = await new Promise((resolve, reject) => {
        this.socketClientCabinet.on('products_get', async ({ server, products }) => {
          if (server === serverID) {
            const {
              productsSymbols,
            } = this.productsTransform(products);

            clearTimeout(productsTimeout);

            resolve(productsSymbols);
          }
        });
      });

用户删除了他的答案，我已经修复了。

      let productsTimeout;

      const timeoutPromise = new Promise((res, rej) => {
        instrumentsTimeout = setTimeout(() => rej(new HttpException('problem', 500)), 1000, )
      })

      const productsPromise = new Promise((resolve, reject) => {
        this.socketClientCabinet.on('products_get', async ({ server, products }) => {
          if (server === serverID) {
            const {
              productsSymbols,
            } = this.productsTransform(products);

            clearTimeout(productsTimeout);

            resolve(productsSymbols);
          }
        });
      });

      const products = await Promise.race([
        timeoutPromise,
        productsPromise
      ])

这是工作。
