NPrinting tasks fail with the following error:
ERROR: Engine.Navigator.QlikSense.SDK.Rendering.MashupLoadException
Environment
Resolution
This is caused by SAML being used as authentication. Only NTLM authentication is supported by the Reporting Web Renderer.
To render images need to create another virtual proxy with NTLM authentication (that would probably have a certain prefix) on any NPrinting connection (and of course linking a proxy to this virtual proxy and following all the requirements for the connection).
See requirements section: Connecting Qlik NPrinting with Qlik Sense
