hi,

sorry for the confusion, our system provides 2 distinct upload operations:
one is a standard HTTP PUT, the type that a browser would form to upload a
file to a server.
The other is a more complex Multipart HTTP POST with 2 parts: JSON Metadata
+ a file.

They both fail occasionally with the same error - the lack of a correct
ending of the HTTP2 operation.

I will try to get in touch with the HTTR developers somehow.

thanks,
Michele
