Instead, get a database connection injected into your service from the container, get its schema driver, and call indexExists() on it. For example, $injected_database->schema()->indexExists($table, $name). See https://www.drupal.org/node/2993033', E_USER_DEPRECATED);
    return Database::getConnection()->schema()
