您好，我用这个代码，智能媒体管理压缩几个jpg是成功的，但压缩5000个jpg，会报错什么原因？

$client = AImmClient::createClient($oss);
$listProjectsRequest = new CreateFileCompressionTaskRequest([
"projectName" => 'xxxxx',
"compressedFormat" => "zip",
"sources" => $sources,
"targetURI" => 'oss://' . $ossbucket . $osstargetURI,
]);

    $status = $client->createFileCompressionTask($listProjectsRequest);
