Why is averageRating always 0? - here-api

Question

I am using the 'Explore Popular Places by Category' API and it always returns averageRating as 0 for all items in the result.
I made this call with various categories such as restaurants and sights-museums, but it always returns 0 for averageRating. Does HERE not provide this detail, and if so, why is it returned in the response?
Some details:
I am making a call to this url:
https://places.ls.hereapi.com/places/v1/discover/explore?at=52.5159%2C13.3777&cat=sights-museums&apiKey={api_key}
and it returns something like this:

Does HERE not provide the averageRatings of restaurants or sights-museums?

Answer 1

From the docs it appears if the place hasn't received a rating it'll be 0
Note: If the place has no ratings (yet), both the average and the count values are zero. But if the place cannot be rated (i.e. a street), the whole rating object is not present.
