Question

这与udacity-cloud开发人员项目有关。我被要求为我创建的id创建一个测试代码，这使我将201和404的错误和单个值抛出错误。此外，还要求我测试签名的URL，这使我犯了同样的错误。不知道为什么。

当我尝试在邮递员中通过id执行测试时，遇到了这3个错误。
FAIL状态码为201 | AssertionError：预期响应的状态码为201，但得到404 失败，该帖子返回ID为|的新项目。 JSONError：意外令牌

import { Router, Request, Response } from 'express';

const router: Router = Router();

// Get all feed items
router.get('/', async (req: Request, res: Response) => {
    const items = await FeedItem.findAndCountAll({order: [['id', 'DESC']]});
    items.rows.map((item) => {
            if(item.url) {
                item.url = AWS.getGetSignedUrl(item.url);
            }

    res.send(items);

    }

    // check Filename is valid
    if (!fileName) {
        return res.status(400).send({ message: 'File url is required' });
    }

    const item = await new FeedItem({
            caption: caption,
            url: fileName
    });

    const saved_item = await item.save();

    saved_item.url = AWS.getGetSignedUrl(saved_item.url);
    res.status(201).send(saved_item);
});

export const FeedRouter: Router = router;

测试打字稿时收到邮递员错误。我该如何解决？
