This morning I am getting the followng warning:

[LWC warning]: Property "_def" of [object:vm undefined (0)] is set to a non-trackable object, which means changes into that object cannot be observed.

It pops up no matter where I navigate in my org.  Last night, everything was fine and I was not receiving it.  

I'm a javascript novice and I've had a difficult time understanding the issue.  Any help would be greatly apprecaited!

Thanks!

Fred
