Couchbase Web Console Issues

I created a Kubernetes cluster with Couchbase (4.5.0-2601) using the instructions located here:

I had no issues creating the cluster (and was able to run simple cli commands to verify that it was running), however when I try to access the web console, I get a blank webpage with the title “Couchbase Console”. When I view the page source, I do get something back but no content (attached) which makes me believe that I’m properly hitting the container but just not getting the expected return.

I also attempted to do this with a non-Kubernetes cluster with just a single node and had the same issue. Any ideas where I may be doing something incorrectly to get this working?
