[ovirt-users] Engine UI exception while viewing unattached hosts in Network tab

Hi, I'm following the Gluster setup blog post ( https://blogs.ovirt.org/2018/02/up-and-running-with-ovirt-4-2-and-gluster...) and am at the 'Storage network' section. I've created a new 'gluster' network, selected the network and navigated to the 'Hosts' tab. The guide tells you to click the 'Unattached' button and then 'Setup Host Networks' for each host. However, clicking the 'Unattached' button fires off a bunch of exceptions rather than displaying my 3 hosts. The message is: "Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : Cannot read property 'N' of null Please have your administrator check the UI logs" Anyone seen this before? Where is the UI log located? Shareef.
