Issue creating data pump export job from sqldeveloper - oracle

Question

I am trying to create data pump export using oracle sql developer wizard below are the grants provided to the user from which I am trying to setup data pump export
grant create session, create table, create procedure, exp_full_database, imp_full_database to TESTE;
grant read, write on directory DOCUMENTS to TESTE;
grant read, write on directory DATA_PUMP_DIR to TESTE;
but after completing wizard i get below error
...
END IF;
EXCEPTION
WHEN OTHERS THEN
NULL;
END;
dbms_output.put_line('REMOVE FINAL TRACE TEXT');
Raise;
END;
Error report -
ORA-31626: job does not exist
ORA-06512: at line 77
31626. 00000 - "job does not exist"
*Cause: An invalid reference to a job which is no longer executing,
is not executing on the instance where the operation was
attempted, or that does not have a valid Master Table.
Refer to any following error messages for clarification.
*Action: Start a new job, or attach to an existing job that has a
valid Master Table.
here is the plsql code generated by wizard at the end
set scan off
set serveroutput on
set escape off
whenever sqlerror exit
DECLARE
h1 number;
errorvarchar varchar2(100):= 'ERROR';
tryGetStatus number := 0;
begin

tryGetStatus := 1;
dbms_datapump.set_parallel(handle => h1, degree => 1);
dbms_datapump.add_file(handle => h1, filename => 'EXPDAT-'||to_char(sysdate,'yyyy-mm-dd-hh24_mi_ss')||'.LOG', directory => 'DATA_PUMP_DIR', filetype => 3);
