Error while scanning device <Room Name> Nullable object must have a value.

[scorp508]

At plugin 4.0.6.0 startup on HS4 4.7.0 I am seeing these entries. Both the "Mud Room Porch" and "Front Door" are rooms in the Hue Bridge. Any thoughts on what may be making it unhappy?

Error: (InitDevices):Gathering information from device Front Door ref:861 of type unknown
Error: (InitDevices):Nullable object must have a value.
Error: (InitDevices):Error while scanning device Front Door Nullable object must have a value.
Error: (InitDevices):Gathering information from device 7 of type unknown
Error: (InitDevices):Nullable object must have a value.
Error: (InitDevices):Error while scanning device Mud Room Porch Nullable object must have a value.


I enabled verbose logging to get the below.

I am guessing tht for some reason the plugin information in the device is missing for some reason.... Would it be a problem to remove both group devices from HS and restart the plugin? After the restart the plugin will recreate the device and put in the correct plugin information again.
If you have events using the devices you will have to connect the new device after the restart. If you have been using the JowiHue actions, there should be no problem (not 100% sure as "rooms" from Philips hue tend to present different now and then.
