我在Postgres中插入或更新时得到Parser.parseErrorMessage

如何解决我在Postgres中插入或更新时得到Parser.parseErrorMessage

我为此感到头痛，我不明白是什么问题。

这是我在Express中的代码

router.patch("/:id",verifyToken,async (req,res) => {
  const { id } = req.params;
  const { title,content,categories } = req.body;
  const authorId = parseInt(req.user.id);

  try {
    let postId = parseInt(id);
    
    if (postId < 0)
      res.json(
        utils.generateError("Something went wrong,try to reload the page.")
      );

    //Validate post data
    const { error } = validatePostData({
      title,});

    //Is there and error? Let the user know it.
    if (error)
      res.status(400).json(utils.generateError(error.details[0].message));

    const slug = await utils.generateSlug(title);
    const summary = await utils.extractSummary(content,240);
    const foundImage = await content.match(/!\[.*?\]\((.*?)\)/);
    let image = "";
    if (foundImage) image = foundImage[1];

    const result = await pool.query(
      "UPDATE posts SET title=$1,slug=$2,summary=$3,content=$4,image=$5,author=$6,categories=$7 WHERE id=$8",[title,slug,summary,image,authorId,categories,postId]
    );

    if (result) res.json(result.rows[0]);
    else throw "Error on updating result";
  } catch (e) {
    console.log(e);
    res.json(utils.generateError("Something went wrong,try again."));
  }
});

但是当我发出补丁请求时，我会在控制台中得到它。

我正在使用Postgres和pg作为节点来处理数据库，奇怪的是该行已在db中更新，但是查询的结果只返回该错误。

有人可以帮我解决这个问题吗？
