Downloading certain books (e.g. "A Glass Half Full" by Sanjay Kathuria in NYU Library) results in the error "Output file size [bytes] must match expected size -1". This happens when the download response is chunked, and does not have a Content-length header.

The problem is that LSHTTPDownload attempts to verify the file size if the expected size is not null:

But if the content length is unknown, the expected size can be set to -1 instead of null:
