file upload failed randomly

Hi Greg,

Thanks for your update.

I already pointed out that the issue was reproduced occasionally for me, and i dont know the exact reason of it.

Further, one of the user in our organization faced this issue frequently.

Please find the below code, that we have used to upload document to Dropbox:

// Create the file metadata
var fileMetadata = new
{
	autorename = true,
	mode = "add",
	mute = false,
	path = $"{pathDisplay}/{fileName}.pdf",
};

// Define the API endpoint and request headers
string url = "https://content.dropboxapi.com/2/files/upload";
var requestObj = new HttpRequestMessage(HttpMethod.Post, url);
requestObj.Headers.Authorization = new AuthenticationHeaderValue(Bearer, accessToken);
requestObj.Headers.Add("Dropbox-API-Arg", JsonConvert.SerializeObject(fileMetadata));

// Use the provided fileStream if it is not null, otherwise use fileContent
if (fileStream != null)
{
	requestObj.Content = new StreamContent(fileStream);
}
else
{
	requestObj.Content = new ByteArrayContent(fileContent);
}

requestObj.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");

// Send the request and get the response
var responseObj = await this.httpClient.SendAsync(requestObj).ConfigureAwait(false);

We have passing Stream and ByteArray Content like below,

// Use the provided fileStream if it is not null, otherwise use fileContent
if (fileStream != null)
{
	requestObj.Content = new StreamContent(fileStream);
}
else
{
	requestObj.Content = new ByteArrayContent(fileContent);
}

There is no issue while uploading the document using ByteArrayContent, they only issue occurs occasionally was using the StreamContent.


In our organization, we have been using Google drive, and OneDrive too, they are working fine without any issue. Same kind of parameters and request are send for all drives.
