I've recently started working with WSO2 and I am encountering a problem with using the VFS to write to a file.

When executing this proxy service I get

VFS is enabled (both Receiver and Sender) and I have tried using
Writing on a text file using VFS in WSO2 ESB 4.8.1
as a reference without luck.
Is there something that I have overlooked?
Thank you,
