Oracle DB expdp ORA-39071: Value for SCHEMAS is badly formed solved

If you receive this error ORA-39071: Value for SCHEMAS is badly formed, you can get rid of it by logging in with the schema that you want to export.
Example: Let's say you want to export schema test with the password 1234. You can write:
expdp test/1234
The value for SCHEMAS will be by default test and you will not receive ORA-39071 anymore.
