The value of "next" is needed to fetch next page data, which i got as STRING. But streamsets pagination supports LIST type. How to fix this ? The output is in the following format

record: {map}

       data: {map}

              created_time: {string} "xxxxxx"   
              message: {string} "xxxxx"    
              id:{string} "xxxxx"

        paging: {map} "xxxxxx"

              cursors: {map}
              next: {string} "xxxxxx"
