        ]);
        $this->forge->addPrimaryKey('id');
        $this->forge->addForeignKey(['branch_codeKey', 'branch_nameKey'], 'branches', 
            ['branch_code', 'branch_name'], 'CASCADE', 'CASCADE');
        $this->forge->createTable('patient');
    }
}

And the following error is in the CLI.
