Schemacrawler not able to retrieve constraints

[Luigi Baldari]

Description

Hello,
I'm trying to retrieve the schema from an Oracle database.
Schemacrawler keeps complaining about errors like this: WARNING: Error executing SQL <......> java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist.
It seems that is missing some permissions on constraint tables. For instance at the beginning it was complaining about query error on table "DBA_CONSTRAINTS". So we granted permissions on this table, then this error disappeared and the same error came up but on another constraint table.
How can I fix that? Is it possible to know the list of constraint tables on which the the schemacrawler user should be granted on?
Thanks

How to Reproduce

schemacrawler --command=script --scripting-language=python --info-level=detailed --log-level=INFO --table-types=TABLE --script=script.py --output-file=.\schema.json --server=oracle --host=my_host.com --port=1234 --database=DB_NAME --schemas=SCHEMA --user=MY_USER <password provided>

Relevant log output

  PRIMARY_KEYS.TABLE_NAME,
  PRIMARY_KEYS.CONSTRAINT_NAME AS PK_NAME,

@luigiba I am not an Oracle expert, so I cannot advise you on how to configure Oracle. SchemaCrawler runs regular tests with the Oracle database, you can look at the relevant SchemaCrawler Oracle tests to see how the database is configured. In particular look at OracleSpecialUsersTest.
