Unable to remap_data while using datapump export

Could anyone help with my datapump export. I've tried many combinations. But, I'm always getting:

ORA-39001: invalid argument value
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 79
ORA-06512: at "SYS.DBMS_DATAPUMP", line 4932
ORA-06512: at "SYS.DBMS_DATAPUMP", line 5768
ORA-06512: at line 38

Any advice on this?

CREATE TABLE foo
(
  bar VARCHAR2(10)
);

INSERT INTO FOO VALUES('hello');
INSERT INTO FOO VALUES('world');
COMMIT;


create or replace package pkg
 is
  function tst(p_val varchar2) return varchar2;
end pkg;
/

create or replace package body pkg
 as
function tst(p_val varchar2) return varchar2 is
begin
 return p_val;
end;
end pkg;
/



DECLARE 
  h1 NUMBER;
  l_status varchar2(200);
BEGIN

    h1 := DBMS_DATAPUMP.OPEN(
      operation => 'EXPORT', 
      job_mode => 'TABLE', 
      remote_link => NULL,
      job_name => 'exp_1', 
      version => 'LATEST'
    );

    DBMS_DATAPUMP.ADD_FILE(
      handle => h1, 
      filename => 'export.dmp', 
      reusefile => 1,
      directory => 'DBOUT',
      filetype => DBMS_DATAPUMP.KU$_FILE_TYPE_DUMP_FILE);
      
    DBMS_DATAPUMP.ADD_FILE(
      handle => h1, 
      filename => 'export.log', 
      reusefile => 1,
      directory => 'DBOUT',
      filetype => DBMS_DATAPUMP.KU$_FILE_TYPE_LOG_FILE
    );

    DBMS_DATAPUMP.METADATA_FILTER(
      handle => h1,
      name => 'NAME_EXPR',
      value => 'IN (SELECT table_name FROM user_tables WHERE table_name LIKE ''FOO%'')',
      object_type => 'TABLE'
    );

    DBMS_DATAPUMP.DATA_REMAP(
      handle => h1, 
      name => 'COLUMN_FUNCTION', 
      table_name => 'FOO', 
      column => 'BAR', 
      function => 'pkg.tst'
    );

    
   DBMS_DATAPUMP.start_job(h1);
   DBMS_DATAPUMP.wait_for_job(h1, l_status);
   dbms_output.put_line( l_status );

END;
/

Regarding the documentation, it should work. No?

https://docs.oracle.com/en/database/oracle/oracle-database/12.2/arpls/DBMS_DATAPUMP.html#GUID-2C61513F-9040-4CE3-8C22-ED1FA5FF81DD

Any suggestion is more than welcome,

The FUNCTION argument must be the correct case, and the SCHEMA argument must be included and must also be the correct case. This procedure call worked for me:

DBMS_DATAPUMP.DATA_REMAP(
  handle => h1, 
  name => 'COLUMN_FUNCTION', 
  table_name => 'FOO', 
  column => 'BAR', 
  function => 'PKG.TST',
  schema => user
);

None of those limitations are mentioned in the documentation so I would say that your original code is correct and that this behavior is a bug.
