EXPDP error ORA-39001: invalid argument value and ORA-01775: looping chain of synonyms

After issuing expdp command the following errors were occured:
ORA-39001: invalid argument value
ORA-01775: looping chain of synonyms

The solution is so simple in this case.

You have to find the synonym which was creating problem.

Issue the following command:

Select owner, object_name, object_type, status

from dba_objects

where object_name like '%SYS_EXPORT_%';

Drop the synonym or all the synonym found in this query.

drop public synonym SYS_EXPORT_SCHEMA_01;

Now run the expdp command again.
