CakePHP 3 - Unable to add new record - forms

Question

When i submit new Job form, hte action passes all the info to the url but the saving action is not happening and no flash message for success or error.
In variable tab in the debugkit all looks ok except maybe the id but it should auto increment anyway...
job (array)
[new] (true)
[accessible] (array)
* (true)
id (false)
The edit Job method works well.
add Job function
public function add()
{
$job = $this->Jobs->newEntity();
if ($this->request->is('post')) {
$job = $this->Jobs->patchEntity($job, $this->request->getData());
$job->user_id = $this->Auth->user('id');
if ($this->Jobs->save($job)) {
$this->Flash->success(__('Job hasbeen saved'));
return $this->redirect(['action' => 'index']);
}
$this->Flash->error(__('Please try again'));
}
$categories = $this->Jobs->Categories->find('list');
$users = $this->Jobs->Users->find('list');
$types = $this->Jobs->Types->find('list');
$this->set(compact('job', 'categories', 'users', 'types'));
$this->set('_serialize', ['job']);
}
view
<div class="col_12 column">
<form id="reg_form">
<fieldset>
<legend><?= __('Add Job') ?></legend>
<?php
echo $this->Form->create($job);
echo $this->Form->control('category_id', ['options' => $categories]);
echo $this->Form->control('user_id', ['options'=>$users]);
echo $this->Form->control('type_id', ['options' => $types]);
echo $this->Form->control('company_name');
echo $this->Form->control('title');
echo $this->Form->control('description');
echo $this->Form->control('area');
echo $this->Form->control('city');
echo $this->Form->control('contact_email');
echo $this->Form->button(__('Submit'));
echo $this->Form->end();
?>
</fieldset>
</form>
</div>
