          in a certain project area (optional, either `projectarea_id`
          or `projectarea_name` is needed if specified)
  
          If `saved_query_name` is specified, only the saved queries match the
          name will be fetched.
  
          Note: only if `creator` is added as a member, the saved queries
          can be found. Otherwise None will be returned.
  
          WARNING: now the RTC server cannot correctly list all the saved queries
          It seems to be a bug of RTC. Recommend using `runSavedQueryByUrl` to
          query all the workitems if the query is saved.
  
          Note: It will run faster when more attributes are specified.
