Export datapump with INCLUDE=DIRECTORY

 Hallo,

I need to export with datapump several objects that belong to owner SYS.

Same of this objects are DIRECTORY. My sintax in expdp command is :

INCLUDE=VIEW:"='SYS.WEBMON_X$KGLPN'"
INCLUDE=VIEW:"='SYS.WEBMON_X$KGLOB'"
INCLUDE=DIRECTORY:"='SYS.dpump'"
INCLUDE=DIRECTORY:"='SYS.TRAS_DIR'"
INCLUDE=DIRECTORY:"='SYS.TRAS_BCK_DIR'"
INCLUDE=DIRECTORY:"='SYS.STORICO_DIR'"

but I always get this error message :

ORA-39001: invalid argument value
ORA-39038: Object path "DIRECTORY" is not supported for SCHEMA jobs.

Need help to correct my sintax for exporting DIRECTORY, is this type of object exportable ?

Thanks
