While working on something else I tried restarting NR on this machine.

I see these errors... To call them by what they seem to call themselves.

```auto

```

As I'm not the sharpest tool in the shed, I can't see how to find out _who_ is causing these errors?

Is the nodes, their config, or something else?

essentially, something in ui\_led.js on line 30, col 29.

you should raise this as an issue with author.

Thanks.

Probably worth updating to the latest version of the node before raising it as it is still under active development. Also the dashboard too of course. No point raising issues when not on latest.

yes - I have a feeling we patched a small fix for loading config a while back but must admit can't find exact version now. (so hopefully this is fixed already, but ....)

Well, just updated the dashboard and LED....

Same thing:

```auto
