Capybara with rails 6.1.4.4 element not found

I'm trying to test the presence of a field called name within capybara but it returns the below error that is the follow:

  1) _form filling the form filling the user elements
     Failure/Error: fill_in 'name', with: 'Leo'
     
     Capybara::ElementNotFound:

Failed examples:

rspec ./spec/features/_form_spec.rb:7 # _form filling the form filling the user elements

Here is the spec that I'm trying to write:

# frozen_string_literal: true

require 'rails_helper'

RSpec.feature '_form', type: :feature do
  context 'filling the form' do
    scenario 'filling the user elements' do
      visit users_path
      fill_in 'name', with: 'Leo'
      expect(page).to have_field('name', with: 'Leo')
    end
  end
end

And the form that I'm creating is like that:

<% if @user.errors.any? %>
  <div id="error_explanation">
    <h2><%= pluralize(@user.errors.count, "error") %> prohibited this user from being saved:</h2>

    <ul>
      <% @user.errors.each do |error| %>
        <li><%= error.full_message %></li>
      <% end %>
    </ul>
  </div>
<% end %>

<%= form_with model: @user, local: true do |form| %>
  <div>
    <%= form.label :name %><br>
    <%= form.text_field :name%>
    <% @user.errors.full_messages_for(:title).each do |message| %>
      <div><%= message %></div>
    <% end %>
  </div>

  <div>
    <%= form.label :email %><br>
    <%= form.text_field :email %>
    <% @user.errors.full_messages_for(:title).each do |message| %>
      <div><%= message %></div>
    <% end %>
  </div>

  <div>
    <%= form.label :age %><br>
    <%= form.text_field :age %>
    <% @user.errors.full_messages_for(:title).each do |message| %>
      <div><%= message %></div>
    <% end %>
  </div>

  <div>
    <%= form.submit %>
  </div>
<% end %>

I tried all solutions here in S.O and none of them seem to work, can someone please help?

The project link is this one: https://github.com/LeoFragozo/leo_test, thanks in advance!

Edit: I tried to use user[name]/user_name in place of "name" in the fill_in and it dosen't seem to work as well.
