Blocking process inputbuf is empty

I was trying to capture blocking query using blocked process report past 1 hour as this link https://www.mssqltips.com/sqlservertip/4480/find-blocking-processes-using-sql-server-profiler/ I can get the blocked process query using sqlhandle but for blocking process query i cannot get it because no sqlhandle and inputbuf doesnt have any SQL statement. Any idea? This is first time i m using this blocked process report.
