I want to get data dump from PDB(Transportable Database). DB version 12.2.0.1.0. Enterprise Edition. Before i get export i applied oracle 27162931 and 27162975 opatch. then after i altered tablespaces except sysaux and system, temp and undotbs1.

sql> alter tablespace users read only;

After logged in to db by using sysdba and then created directory and granted read, write access.

SQL> CREATE OR REPLACE DIRECTORY exp_dir AS 'D:\export_db';

SQL> GRANT READ, WRITE ON DIRECTORY exp_dir TO system;

Then i logged from system and ran export command like below,

sql> host expdp system/XXXXXX@D1943 dumpfile=DB12cdmp.dmp directory=exp_dir transportable=always full=y version=12.2.0.1.0 logfile=exp_test1.log

but i'm getting error like below, Processing object type
