Random web page crashes

At random times, we get a web page crash. It doesn’t seem to follow from anything in particular and happens on all browsers I’ve tried. I can’t replicate it, but if I just go about using Grafana it will eventually happen. The error that comes up is…

An Unexpected error happened
TypeError: t.map is not a function
