Can not delete or rename lights in phoscon

After updating to newest beta 2.15.02 it’s not possible for me to delete or change the name of the lights.
Clicking on a light doesn’t open the lights options…

Developer mode in the web browser is showing this error by browsing to lights and clicking on those:

With kind regards from Sweden,

Frank

Yes i have the same problem,

Just updated to Beta 2.17. Still not working

Same for me, updating to beta 2.17 hasn’t fixed the problem.
