When the parent scan found not gateway, e.g. because the scanned host is the local host, then an exception like this was produced by the background job:

ERROR heute on site heute: type object argument after * must be an iterable, not NoneType
Traceback (most recent call last):
  File "/omd/sites/heute/lib/python/cmk/gui/wato/pages/parentscan.py", line 107, in _process_task

    gateway = ParentScanResult(*gateways[0][0]) if gateways[0] is not None else None
