Using Each Loop in EJS Template and Express JS - node.js

Question

I am working on a form validation and i am trying to loop the errors in my template but i keep getting error.
In my posts routes i have this
router.post('/create', async (req, res)=>{
try{
var errors = [];
if(!req.body.title){
errors.push({message: 'Please Add a Title'})
}
if(errors.length > 0){
res.render('admin/posts/create',{errors: errors})
} else{
let filename = 'Nissan.jpeg';
if(!isEmpty(req.files)){
const file = req.files.file
filename = Date.now() + '-' + file.name
file.mv('./public/uploads/' + filename, (err)=>{
if(err) throw err
})
}
let allowComments = true;
if(req.body.allowComments){
allowComments = true;
} else{
allowComments = false;
}
const newPost = await new Post({
title: req.body.title,
status: req.body.status,
allowComments: allowComments,
body: req.body.body,
file: filename
});
const savedPost = await newPost.save();
// console.log(savedPost);
res.redirect('/admin/posts');
}
} catch (error){
console.log(error);
}
});
And in my ejs template with url (admin/posts/create) i have this
<% errors.forEach(errors => { %>
<%-errors.message %>
<% }) %>
But i keep getting this error message in my browser
ReferenceError: /blog/views/admin/posts/create.ejs:2
1| <%- include('../admin-partials/head') %>
>> 2| <% errors.forEach(error => { %> <%-error.message %> <% }) %>
3| <div class="dashboard-col-2">
4| <h1>Create Post</h1>
5|
errors is not defined
What can i do to solve this error message?
When i do console.log(errors) i get this
[{ message: 'Please Add a Title' } ]

if(errors.length > 0){
res.render('admin/posts/create',{errors: errors})
You are only rendering errors if it's > 0, otherwise it's undefined.
