在 model xxx 上找不到查询 xxx 的文档

Question

I get the error you can read it from the title. It appears whenever i try to .save() a document.

let [post] = (
    await User.findOneAndUpdate(
      { _id: USER_ID },
      {
        $push: {
          posts: {
            title,
            content,
            userId: USER_ID,
            titleUrl,
            thumbnail: {
              webp: WEBP_PATH,
              jpeg: JPEG_PATH,
              placeholder: PLACEHOLDER
            }
          }
        }
      },
      { new: true }
    )
  ).posts.slice(-1);
  let newBlog = new Blog(post);
  await newBlog.save();

What i tried:

newBlog.update() no error appeard, but also no change.

I also tried to set a different version key at my model like { versionKey: "_someKey"} no success.

What could it be?

await Blog.create(post) also didnt work. Same error.

For the people that are in the same situation, my solution was adding .lean() at the end of the query

let [post] = (
    await User.findOneAndUpdate(
      { _id: USER_ID },
      {
        $push: {
          posts: {
            title,
            content,
            userId: USER_ID,
            titleUrl,
            thumbnail: {
              webp: WEBP_PATH,
              jpeg: JPEG_PATH,
              placeholder: PLACEHOLDER
            }
          }
        }
      },
      { new: true }
    ).lean()
  ).posts.slice(-1);
