Removed url replace.

          let link = result.collections[i].links[j];

          if (link.rel == "items") {

            var url = result.collections[i].links[j].href;

            // this is temporary until stac.astrogeology is working with pagination

            url = url.replace(

              "https://stac.astrogeology.usgs.gov/api/collections",

              "https://jat52qc8c0.execute-api.us-west-2.amazonaws.com/dev/collections"

            );

            url = url + queryString;

            urlArray.push(url);

          }
