Those were the parameters I used:

lb_iter 4 1.0 1 --vt_lb --vt_lb_interval=1 --vt_lb_name=RotateLB --vt_lb_data --vt_lb_data_compress=false --vt_lb_data_dir=... --vt_lb_data_file=...

Looks like entire entity is not valid:

{
   "entity": {
      "home": 0,
      "id": 0,
      "migratable": false,
      "type": "object"
   },
   "node": 0,
   "resource": "cpu",
   "time": 0
}

After some testing I see it always happens for the last entity in phase 0.
