how to resolve an error to use spatie laravel

问题

I am using spatie library in laravel lumen to create file into image. But it is giving error.

$destinationPath = storage_path('uploads');
$new_path = str_replace('\\', '/', $destinationPath);

Browsershot::url('https://www.example.com/')
    ->setScreenshotType('jpeg', 100)
    ->save($new_path);

Error is: The given path 'your storage file path' did not contain an extension. Please append an extension.
