noVNC encountered an error: Script error.

Since upgrading to antMan 0.9.1a, when I try to launch a noVNC connection to my Windows 10 antsle, I am presented with a floating dialog in the middle of the VNC window that reads "noVNC encountered an error: Script error."

I am able to work around the error dialog, but it cannot be closed.

Is there a place I should look for more information on this error?

This is a browser issue, specifically with Chrome. I had the same issue using EPIC browser (Chrome based), works fine on newer Chrome and Firefox.
