火山引擎的豆包图片生成报错

[bbuugg]

laravel ai版本 "laravel/ai": "^0.2.2",

配置文件如下
ai.php

     'doubao' => [
            'driver' => 'openai',
            'key'    => env('DOUBAO_API_KEY'),
            'url'    => env('DOUBAO_BASE_URL', 'https://ark.cn-beijing.volces.com/api/v3'),
        ],

生成的代码如下

    $image = Image::of('A donut sitting on the kitchen counter')
        ->size('1024x1792')
        ->queue(model: 'doubao-seedream-3-0-t2i-250415')
        ->then(function (\Laravel\Ai\Responses\ImageResponse $imageResponse) {
            dd($imageResponse->firstImage());
        });

出现的错误如下：

Laravel\Ai\Responses\Data\GeneratedImage::__construct(): Argument #1 ($image) must be of type string, null given, called in vendor/laravel/ai/src/Gateway/Prism/PrismGateway.php on line 200

这是我打印的一个对象

  +base64: null

}

豆包返回了一张图片，没有base64，导致后续报错
