Bad Request - Security Component (Cakephp 3)

I have a project on my localhost that uses the Security Component and everything works fine. I have the same project duplicated and its the other way round. All the forms, except the login is being blackholed.

Here’s what my setup looks like.

App\src\Controller\AppController.php

* @return void
*/
public function initialize() {
    $this->loadComponent('Security'); 
    $this->loadComponent('RequestHandler');
    $this->loadComponent('Flash');

    .....
}

App\src\Controller\UsersController.php

public function initialize() {
    parent::initialize();        
    $this->Auth->allow(['logout', 'register', 'forgotPassword', 'resetPassword', 'activateAccount']);
}

public function beforeFilter(Event $event) {
    parent::beforeFilter($event);
    $this->Security->setConfig('csrfUseOnce', true);
    $this->Security->setConfig('unlockedFields', ['payment_action', 'g-recaptcha-response']);
    $this->Security->setConfig('blackHoleCallback', 'blackhole');
}

I’ve confirmed that the csrf is generated as hidden field along with _Token fields (same as in the other project, but it just doesn’t work

No fields are generated statically, no names are overidden, forms are generated using
$this->Form->create()
Forms are closed using
$this->Form->end();

Here’s an example of the a form, its got just one field, but it is always bllackholed

<?= $this->Form->create($user, ['id' => 'tfaForm', 'class' => "form-horizontal form-material", 'autocomplete' => 'off']); ?>
   <div class="form-group ">
      <div class="col-xs-12 col-md-3">
        <?= $this->Form->text('tfa', ['labelOptions' => false, 'class' => 'form-control', 'placeholder' => "6  digit Code", 'autofocus']); ?>
	  </div>
	</div>
	<div class="form-group m-t-10">
	    <div class="col-xs-12 col-md-4">
            <?= $this->Form->button('Submit', ['class'= > 'btn waves-effect waves-light btn-primary btn-sm']); ?>
	    </div>
	</div>
<?= $this->Form->end(); ?>

The validatePost() method of the Security Component keep returning false. Is there something I’m not getting? I would appreciate a technical explanation.

Thanks in advance.
