<s>[INST] I have an AJAX POST request in Cakephp and I'm getting null values in the request. My code looks something like this:

```php
public function TRACE_getUsageSummary() {
    $this->autoRender = false;
    if ($this->request->is('post')) {
        $data = $this->request->input();
        debug($data);
        //Input data is null
    }
}
```
I've checked everything on the frontend side, the data is being sent correctly. I find it weird that the request is being treated as a post but the data is still null. Am I missing something obvious?[/INST]
