using Dropbox.NET. Calling UploadAsync with a commitInfo, and FileStream.
commitInfo = new CommitInfo(path, writeMode.AsOverwrite, false, null, false);
UploadAsync(commitInfo, aFileStream);
The first upload of the file works fine. I then edit the file, by changing a line in it, and attempt another upload. It fails with:
Dropbox.Api.ApiException`1[Dropbox.Api.Files.UploadError]: path/conflict/file/
