I think this happens only when zniffer is not connected for some reason, thanks for your issue. Fixed

Thanks for the quick fix. I think I'm also running into this currently on the zwavejs/zwave-js-ui:latest image from docker hub (I have zniffer disabled). The image is probably still one version behind. I'll await the new image.

All working now, thanks for the fix.
