Hello,

CLI Command:

```
curl -X POST "https://api.domain.com/vm/create" -H "X-Auth-Key: Bearer 8fbb80d7f378f2271236388093439422" --data '{"usname":"example"}'

```

Code:

```
$app->post('/user/create', function ($request, $response, $args) {
	$json = $app->request->getBody();
	$data = json_decode($json, true); 
	$sth = $this->mdb->prepare("INSERT INTO `user` (`username`,`date`) VALUES (:uname,'0000-00-00 00:00:00')");
	$sth->bindParam("uname", $data['usname']);
	$sth->execute();
	return $name;
});

```

Result:

```

The error says `Call to a member function getBody() on null`, as you’ve passed `$request` to your function, but not `$app` (which isn’t needed).

Try

```php
$app->post(’/user/create’, function ($request, $response, $args) {
    $json = $request->getBody();

```
