Submitting a form results to a url segment undefined in NodeJs - node.js

Question

I am setting up a simple form submission, when I submit the form the url becomes undefined
This is the view: http://localhost:3000/dashboard/tours/categories
router.get('/tours/categories', function (req, res) {
res.render('agents/tourcategories', {
page_link: 'wishlist'
});
});
This is the form:
<form method="POST" action="/dashboard/tours/categories" >
<div class="box_general padding_bottom">
<div class="row">
<div class="col-md-12">
<div class="form-group">
<label>Category Name</label>
<input type="text" name="categoryname" class="form-control" placeholder="e.g Hiking">
</div>
</div>
</div>
</div>
<div class="modal-footer">
<button class="btn btn-secondary pull-left" type="button" data-
dismiss="modal">Cancel</button>
<button id="" type="submit" class="btn btn-primary" >Save</a>
</div>
</form>
when I submit the form tne url changes to: `
http://localhost:3000/dashboard/tours/undefined
router.post('/tours/categories',function (req, res) {
console.log("We are here");
const category = new CategoriesDB({
categoryname: req.body.categoryname,
addedby: res.locals.useremail
});
// Save a Customer in the MongoDB
CategoriesDB.save(function (err) {
if(err){
console.log(err);
return;
}else{
res.redirect('/tours/categories');
}
})
});
I realy dont know where the undefined came from, I have checked everything seems to be okay. It keeps popping up in the url everythime i submit the form

From the snippets of the code you have posted, It might be because u have not used the middleware
router.all("/dashboard*");
But if u have used that and the GET request is working but not the POST then u will need to post more snippets of your code, mainly the middleware you defined to handle the routes
