[json响应给出错误[页面上的对象Object]

Question

我正在尝试通过cloudinary multer在应用程序上上传图像和视频，但仅在图像（<1MB）响应带有[object Object]的页面时才适用于图像。我认为错误与响应有关，但我无法纠正。

发布路线

router.post("/", middleware.isloggedin, upload.array('images'), async function(req, res) {
    try {
        req.body.ca.images = [];
        for (const file of req.files) {
            req.body.ca.images.push({
                url: file.secure_url,
                public_id: file.public_id,
                format: file.format
            });

        }
        req.body.ca.author = {
            id: req.user._id,
            username: req.user.username
        }
        req.body.ca.created = new Date();

        const campground = await Campground.create(req.body.ca);

        res.redirect('/c/' + campground.id);
    } catch (err) {
        req.flash("error", err.message);
        res.redirect("back");
    }
});
