I'm using node-red-contrib-zigbee2mqtt for my Zigbee devices, works all great.
In the Zigbee bridge node there's a tab with the option to generate a map of my Zigbee network, this works also great.
However on this tab there's also a button "Open in full screen", if this is pressed we get an empty web page with the error Cannot GET /zigbee2mqtt/showMap, in the url of my browser is http://192.168.1.127:1880/zigbee2mqtt/showMap?controllerID=fcbfb445.44989 , this all looks fine to me.
I'm sure it was working a couple of months ago.
What can be the problem or where to look to tackle the problem?
