Updating Thing Parameters in Paper UI Error

Gents!

Been plugging along a bit messing around when I have time away from work. Slowing down due to the holidays (YAY!)

I was making a change to the HEM parameter to tweak Voltage to calculate power usage, and it seems to update but then throws 404 error in Paper UI.

When I switch to habmin - It works. The below messages in the log are as follows.
Attempt to change in Paper UI - error
Attempt to HABmin - Success

I might try updating the nightly build but figured I’d ping back here to see if anyone had any insight.

Hope everyone is enjoying (or enjoyed) their weekends!
