testFTP server UNC error in module 12 DIY (Fundamentals) not working

I am getting an error in the Fundamentals Module 12 DIY exercise. In the starter solution there is a test.xml configuration provided including a testFTP flow that is testing the in memory FTP server. It is configured to run on a scheduler basis.

I am getting an exception on this when running the project and wondering if there is some configuration that is missing or if there is a problem with the mock FTP server implementation provided. As per the console trace below - the mock server is up and running just not accepting read operations. (Why is it looking for a Windows UNC on an FTP server?)

I am running on version 4 with the latest Anypoint Studio (7.3.1)
