expdp fail with ORA-39125 ORA-31642 ORA-06512 ORA-21780

I have DB called wtwora, iam trying to export databse with expdp.

I created proper user:

create user myuser identified by somepassword;

grant connect,dba,resource,exp_full_database,imp_full_database to myuser;

create or replace directory DMP as 'F:\DMP\';

grant read, write on directory DMP to myuser;

Then iam checking what schemas i want to export:

select username from dba_users;

Then i am making export:

expdp myuser@wtwora directory=DMP dumpfile=wtwora.dmp logfile=wtwora.log schemas=WTWORA,SIMONE

And it fails with in 490GB (databse have 1.8TB):
