[UI] Seeing error - [$compile:tpload] Failed to load template - in the UI logs on the Ubuntu Longevity cluster

Build : 5.0.0-3490

Seeing this error on the UI logs multiple times. Not sure what caused it.

This is the Ubuntu System Longevity test cluster (http://172.23.106.14:8091). The env is live if you want to take a look.
