BulkAccount `SyncTime` value is null after downloading entities

[franckyj]

While doing some tests I encountered a case where an exception was thrown when downloading the entities after having sent a bunch of modifications.

As it turns out, the error was coming from reading the entities with the BulkFileReader:

using (var reader = new BulkFileReader(bulkReportCSVFile.FullName, ResultFileType.FullDownload, DownloadFileType.Csv))
{
    return reader.ReadEntities().ToList();
}

This is the stack trace I got:

It seems this value isn't suppose to be null. The SDK version I'm using is 10.4.12.0

Let me know if you need anything else.

Thanks, Francois

I apologize for the delayed reply. Please clarify did you request a full download or are you trying to parse the upload result file? If the file is for upload results, you'll want to set ResultFileType.Upload instead of ResultFileType.FullDownload. If the file contents are from a full download are you still able to repro this issue with version 10.4.13? Upload result will not have Account with sync time. Full download should have Account with non-null sync time. Did you open the result file and confirm the field is empty/null? That would be an issue with the Bulk service itself (not SDK). Either way if you can provide more details about the repro we can investigate.
