My room lighting automation is suddenly no longer accessible. Clicking on the automation returns the following:
An unexpected error has occurred trying to load the app. Check Logs for more information.
Error: Cannot get property 'displayName' on null object
The only error I can find in the logs is:
java.lang.NullPointerException: Cannot get property 'displayName' on null object on line 1442 (method mainPage)
What does this mean and how do I fix it?
Strangely, the portion of the automation that always worked still works. I just can't get into it to edit it.
Searching around the forums indicates responses to some similar questions advise running the configure button for devices. There are four devices associated with this automation but only three have configure buttons, which I have clicked but that does not solve it.
One of the devices associated with the automation is a Bond Smart Fan. I had to delete and readd that today when I added a Bond Hub. I suspect this may have something to do with this but don't know how to fix it. I already clicked configure on this Bond device but that did not help.
