如何使用Google Places API获取正确的数据

I am currently implementing proxy for my application with google cloud platform. I followed this tutorial. In web preview mode for "?location=44.446204,26.096263&radius=500" I got multiple locations. Unfortunately, in deployment if I try to append the same path filter to the base url, I got {"next_page_token":"","results":[]}. Did I miss something?
