javascript - 使用来自 .net 核心 API 的预签名 url 将多部分数据从 Javascript 上传到 S3 时出错

Question

我正在使用 .NET（API/后端）中的以下代码生成预签名 URL。

var preSignedUrlRequest = new GetPreSignedUrlRequest
{
    BucketName = bucketName,
    Key = keyName,
    UploadId = data.UploadID,
    PartNumber = data.PartNumber,
    Expires = DateTime.Now.AddMinutes(1440),
    //Protocol = (Protocol.HTTPS),
    Verb = HttpVerb.PUT
    //ContentType = data.ContentType,

};
var url = s3Client.GetPreSignedURL(preSignedUrlRequest);

并发送回前端（在http://127.0.0.1:5500/index.html运行的 Javascript 文件）将文件字节直接上传到 S3。

for (let index = 1; index < NUM_CHUNKS + 1; index++) {
    start = (index - 1) * FILE_CHUNK_SIZE
    end = (index) * FILE_CHUNK_SIZE
    blob = (index < NUM_CHUNKS) ? state.selectedFile.slice(start, end) : state.selectedFile.slice(start)

    const sData = {
            fileName: state.fileName,
            partNumber: index,
            uploadID: state.uploadId,
            contentType: 'application/x-www-form-urlencoded; charset=UTF-8'
        }
    let res = await axios.post(`${state.backendUrl}/FileUpload/GetUrlForEachPart`, sData);
    let presignedUrl = res.data;
    if(!presignedUrl) return;

    let uploadResp = axios.put(
        presignedUrl,
        blob
         , { headers: { 'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8'}}
    );
    promisesArray.push(uploadResp)
}

但得到以下错误：

</Error>

我正在尝试从昨天开始修复它并尝试许多 stackoverflow 解决方案。但没有运气。

如果有人弄清楚我的错误，那将是一个很大的帮助。谢谢

注意：我的凭据没有用。我可以从后端上传文件字节而无需预先签名的 url。
