Anyone with experience using DBMS_DATAPUMP.GET_DUMPFILE_INFO procedure?

Question

I want to get a little bit of information about the dump file prior to trying to restore. I think the get_dumpfile_info procedure will provide me with the information I seek. However, when I try to run the code below, I get an error on the get_dumpfile_info line with the error code ORA-24337: statement handle not prepared. The only information I can find on that error code is:
Oracle Database Error Code ORA-24337 Description : statement handle not prepared
Error Cause: A statement cannot be executed before making preparing a request.
Action: Prepare a statement before attempting to execute it.
Which is about as useful as a one-legged rooster in the hen house.
All I can find on the procedure itself, is just the API makeup for the procedure (no real example). One example site follows:

Anyone ever tried to use this and got it to work? If so, would you please share what you did that I am not doing? Thanks.
Replace the <bracketed info with your info> in the variable setup
set serveroutput on
declare
     infoTable           ku$_dumpfile_info;
     typeFile           NUMBER; --file info type : 0=unknown; 1=data pump dump file; 2=original export dump file
     SchemaOwner     varchar2(50);
     BackupDir          varchar2(1000);
     BackupFile          varchar2(1000);
begin
     BackupFile := '<file name - no extension (added during the utility call)>';
     BackupDir := '<unc path to the backup location>';
     SchemaOwner := '<valid schema>';
     EXECUTE IMMEDIATE 'GRANT CREATE ANY DIRECTORY TO ' || SchemaOwner;
     EXECUTE IMMEDIATE 'CREATE OR REPLACE DIRECTORY test_dir AS ''' || BackupDir || '''';
     EXECUTE IMMEDIATE 'GRANT READ, WRITE ON DIRECTORY test_dir TO ' || SchemaOwner;
     DBMS_DATAPUMP.GET_DUMPFILE_INFO(
          filename => BackupFile || '_pmp.dmp',
          directory => 'TEST_DIR',
          info_table => infoTable,
          filetype => typeFile);
     dbms_output.put_line( 'file type: ' || to_char(typeFile) );
end;

Can't believe I spent all day looking at a missed single quote. Figure Oracle would be a little better in their error message. :-/
