i am getting an error while i am updating my data using express node.js

Question

i am trying to update my category name but when i click on the submit button it gives me an error however i tested my code using postman and it actually updated but in that case i have to pass the product's id manually.

the callback function of the update category:

    exports.updateCategory = (req, res, next) => {

    console.log('GET update CATEGORY /update-category');

    if (!req.body) {
        return res
            .status(400)
            .send({ message: "Data to update can not be empty" })
    }

    const id = req.params.id; //req.body.id >> body means in the html/ejs file the name should be id

    categorySchema.findByIdAndUpdate(id, req.body, { userFindAndModify: false })
        .then(data => {
            if (!data) {
                res.status(404).send({ message: `Cannot Update user with ${id}` })
            }
            //updating the data
            else {
                res.render('category/edit_category.ejs', {
                    category: data //variable that i am going to use is category in the ejs
                })
            }

        })

    .catch(err => {
        res.status(500).send({ message: "Error update user information" })
    })


}

the update form >>

    <form action='<%=`/halalMunchies/update-category/${category._id}`%>' method="post">
.
.
.
<label class="control-label" for="categoryName"> Category Name </label>
        <input type="hidden" name="id" value="" id="id">
        <input id="categoryName" class="form-control" value="<%= category.categoryName%>" name="categoryName" required autofocus="autofocus" />

the router.js

    //PUT UPDATE CATEGORY

router.put('/update-category/:id', categoriesController.updateCategory);

router.get('/update-category/:id', categoriesController.updateCategory);

the error message on page is :

Cannot POST /halalMunchies/update-category/618632e3a5ad00fa5368ad5c

As the error message tells you, you did not provide a post endpoint in your router. Since you're using the post method in your form, you need to add the following in your router.js:

router.post('/update-category/:id', categoriesController.updateCategory);
