Call to a member function children() on bool

在调用多文件打包压缩接口时，报错：Call to a member function children() on bool

代码示例：

$this->cosClient->createFileCompressJobs([
    'Bucket'    => $this->bucket,
    'Tag'       => 'FileCompress',
    'Operation' => [
        'FileCompressConfig' => [
            'Flatten' => '0',
            'Format'  => 'zip',
            'Keys'    => $keys,
        ],
        'Output'             => [
            'Region' => $this->region,
            'Bucket' => $this->bucket,
            'Object' => $key,
        ],
    ],
]);
