This is the code:

$app-\>post(’/photo’, function (Request $request, Response $response) {

```
    $directory = $this->get('upload_directory');

```

echo 'hi ';  
$uploadedFiles = $request-\>getUploadedFiles();

```
    $uploadedFile = $uploadedFiles['picture'];
    if($uploadedFile->getError() === UPLOAD_ERR_OK) {
        $filename = moveUploadedFile($directory, $uploadedFile);
        $response->write('uploaded ' . $filename . '<br/>');
    }

});

```

function moveUploadedFile($directory, UploadedFile $uploadedFile){  
$extension = pathinfo($uploadedFile-\>getClientFilename(),  
PATHINFO\_EXTENSION);  
$basename = bin2hex(random\_bytes(8));  
$filename = sprintf(’%s.%0.8s’, $basename, $extension);  
$uploadedFile-\>moveTo($directory . DIRECTORY\_SEPARATOR . $filename);

```
return $filename;

```

}

The error is telling you that variable _$uploadedFile_ is null. If you are uploading files means that html form isn’t sending files.
