Would you be able to possibly direct message me with some more details as to the example you've seen when making this request and returning the empty breakdown value?
If at all possible, could this include the response and the request that was made when this was received?
Unfortunately it is not possible using the Analytics API to fetch results that will return empty values for the breakdown.
These endpoints are designed to fetch data that matches the parameters defined in the request URL, in the event there are no results, an empty response is returned.
I am happy to pass you query along to our team internally, though.
