'NoneType' object is not iterable

I started getting the below error, as of a couple of days ago:

TypeError: 'NoneType' object is not iterable

Any suggestions what it could be?

EDIT: To be clear. It worked and then stopped a couple of days ago. Feels like the API might've changed.

Hm, looks like one of my vacuums added a new map. It should detect the existing one, but it didn't and instead created a new map. The new map contains 0 zones.
