Does not display database schemas for migration in MongoDB Realtional Migrator

When executing MongoDB Realtional Migrator with Oracle, it does not display the schemes to select and continue with the migration, here I leave images of what was done in ubuntu.

Hi @edisoncsi, thanks for trying Relational Migrator and sorry to hear you’re having issues.
Could you let me know which version of Oracle you are trying to connect to, and what version of the JDBC driver you have installed?
