Mapillary Python SDK issue with traffic_traffic_signs_in_bbox method

Hello!

I think the photo is pretty self-explanatory. When I pass a large bbox (us west coast region) to the mly.interface.traffic_signs_in_bbox method, I get the KeyError: 'value' error, as you can see in the picture. Doing the same thing for a much smaller region (Monaco) seems to work. Does anyone have any ideas why?
