Environment

Release : 12.3

Component : Webservice REST v4

Cause

By Design

Resolution

*Behavior is by design*

Between version 3.X and version 4.X of the Webservice components the Webservice was divided in two - WebserviceREST and WebserviceSOAP.
These are completely new applications - and should not be considered as a major upgrade.

The problem in this case is the WebserviceREST was designed mostly for accessing text-based files - text, xml or json, and NOT for downloading files.
For downloading files there is the RA.FTP component.

As a solution we can recommend to use cURL instead of the Request Sheet for downloading files.
Another option is to configure an OS specific job and use wget to download the files.
There is no other way at the moment.
