tried on TWO ISY after updating today.

Zero's everywhere. Restarted, reinstalled, different slots, no luck

The problems looks like it's happening in the UDI node.js interface library. I'm guessing they never tested it with the upgrade to verify that it works.

I'm no longer maintaining that library so you'll probably have to contact UDI.

One thing I just thought of, for ST-Inventory to work, you do have to check the checkbox on the config tab to allow the plug-in to access the IoX/ISY.

and make sure you hit the save button after checking the check box.

it was checked on both EISY and not working.

I did two things today. Upgraded to the latest pg3x .22 to .23

then I deleted the nodeserver, reinstalled (Same slot), and checked box.

Now its working!!!

So don't know if the .23 fixed it or the reinstall. But I had reinstalled before.

Neither Benoit or I was able to reproduce this, ST-Inventory was working for both of us.

The error looks like it could be caused by the checkbox not being checked. I know at least once, I checked the box, but forgot to save it causing a very similar error.
