Node.js de mongodb ile id üzerinden veri almaya çalışırken sebebini bulamadığım bir hata alıyorum

Nerede hata yapıyorum ?

Önce URL'ime id'yi bu şekilde ekliyorum :

<ul>
  <% blogs.forEach((blog) => { %>
    <li>
      <a href="/blog/<%=blog._id%>"><%=blog.title%></a>
      <p><%=blog.short %></p>
    </li>
  <% }) %>
</ul>

id'yi ekledikten sonra URL'imi bu şekilde yakalıyorum :

app.get("/blog/:id",(req,res)=>{
    const id = req.params.id;
    Blog.findById(id)
        .then((result) => res.render("blog",{ blog: result , title: "Detay"}))
        .catch((err) => console.log(err));
});

ve render ettiğim sayfada değişkenleri bu şekilde kullanıyorum :

<section>
  <h1><%=blog.title%></h1>
  <p><%=blog.long%></p>
</section>

fırlatılan hata ise şöyle :
