【问题描述】：
我目前正在关注 Autodesk forge 上的为查看器准备文件教程。这是链接： https://forge.autodesk.com/en/docs/model-derivative/v2/tutorials/prep-file4viewer/ 我没有使用 cURL 发出请求，而是使用 jquery ajax 制作了 javascript 代码来发出请求。我将每个请求都设为一个函数，并带有一个按钮来触发每个请求，如下代码所示。目前，每个请求都可以正常工作，除了转换为 svf 请求。当我尝试发出该请求并检查我的请求状态时，将打印以下消息：
{
"urn": "dXJuOmFkc2sub2JqZWN0czpvcy5vYmplY3Q6cHJvamVjdGZpbGVzMTIzNC9fTUMtMTQwMDYlMjBGT0xERVIlMjBBU1NZJTIwLSUyMEhTQ0YtMTIuaWFtLmR3Zg",
"derivatives": [{
"hasThumbnail": "false",
"name": "_MC-14006 FOLDER ASSY - HSCF-12.iam.dwf",
"progress": "complete",
"messages": [{
"type": "error",
"code": "DWF2D-Not_A_DWF_Error",
"message": "Unable to open, not a DWF/DWFx file."
}, {
"type": "error",
"message": "Extractor error code -11",
"code": "TranslationWorker-InternalFailure"
}],
"outputType": "svf",
"status": "failed"
}],
"hasThumbnail": "false",
"progress": "complete",
"type": "manifest",
"region": "US",
"version": "1.0",
"status": "failed"
使用邮递员，我可以提出相同的请求，一切都会正常进行。然后，当我尝试再次翻译文件时，只要它来自同一个存储桶，它就可以工作。我需要能够立即从代码上传和翻译文件，而不必先在邮递员中翻译。我什至试图复制翻译请求的邮递员代码，但是当文件不在我的存储桶中时，我得到了同样的错误。下面是我的简单网页代码。
