Google Assistant sometimes fail to sync, where to check any log?

  • Platform information:
    • Hardware: amd x86
    • OS: windows 10
    • Java Runtime Environment: 1.8.0_191
    • openHAB version: 2.4.0

As in object, sometimes saying “Sync my devices” to my Google Assistant it fails to accomplish (probably due to my bad configuration in items file, usually it works flawlessly), but is there any google log to easily check where’s the problem?
I can’t find in nor locally.

Many thanks in advance to anyone!
