POST request on /post/:id/comment works, although i get an Cannot GET error

Question

i have this router.post:

router.post("/:id/comment", async (req, res) => {
  // find out which post you are commenting
  const id = req.params.id;
  // get the comment text and record post id
  const comment = new Comment({
    author: req.body.author,
    text: req.body.text,
    post: id,
  });
  // save comment
  await comment.save();
  // get this particular post
  const postRelated = await Post.findById(id);
  // push the comment into the post.comments array
  postRelated.comments.push(comment);
  // save and redirect...
  await postRelated.save(function (err) {
    if (err) {
      console.log(err);
    }
    res.redirect("/");
  });
});

It works, and it adds the comment to the comments array of post, although in Postman i get an error: Cannot GET. I do not really understand why and I rather not have any errors in my app, although the post request works.

ADDITIONAL INFO The Post model:

const { Schema, model } = require("mongoose");

const postSchema = new Schema({
  photoUrl: {
    type: String,
    required: true,
  },
  description: String,
  likes: Number,
  creationDate: Date,
  author: String,
  comments: [
    {
      type: Schema.Types.ObjectId,
      ref: "Comment",
    },
  ],
});

module.exports = model("Post", postSchema);

The comment model:

const { Schema, model } = require("mongoose");

const commentSchema = new Schema({
  text: {
    type: String,
    required: true,
  },
  creationDate: Date,
  post: { type: Schema.Types.ObjectId, ref: "Post" },
  author: String,
});

module.exports = model("Comment", commentSchema);

Answer 1

You seem to only be creating a controller for the HTTP method POST if you would want to accept GET requests as well you should create a new controller and replace: router.post with router.get.

Caveat

Keep in mind that GET requests do not accept request bodies.
