Schlage BE469 System Hardware Failure

Just saw this in my log and it looks ominous, but the Schlage BE469 lock continues work with no apparent issue. Anyone have an idea as to what is wrong with lock?

Lock: Alarm events: Lock_GarageAttached_Inner=[{"notification":"SYSTEM__HARDWARE_FAILURE","level":"0","type":"SYSTEM","event":"1","status":"255"}]
