o Tipo var não herda os atributos key, value, partition e offset da ConsumerRecords

Estou usando o IntelliJ 2019.3.3 com o Java 12. Quando sigo os passos do vídeo, ele consegue pegar a referencia do record, mas não consegue acessar os atributos que deveriam vir junto (key, value, partition e offset)

for (var record : records) {
            System.out.println("###########################################");
            System.out.println("Processing new order, checking for fraud");
            System.out.println(record.key()); //erro aqui  cannot find symbol, symbol:   method key(), location: variable record of type java.lang.Object
            System.out.println(record.value()); //erro aqui  cannot find symbol, symbol:   method value(), location: variable record of type java.lang.Object
            System.out.println(record.partition()); //erro aqui  cannot find symbol, symbol:   method partition(), location: variable record of type java.lang.Object
            System.out.println(record.offset()); //erro aqui  cannot find symbol, symbol:   method offset(), location: variable record of type java.lang.Object
            try {
                Thread.sleep(5000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            System.out.println("Order Processed");
            System.out.println("###########################################");

Tentei outras soluções como

records.foreach( record -> {
System.out.println("###########################################");
            System.out.println("Processing new order, checking for fraud");
            System.out.println(record.key()); //erro aqui  cannot find symbol, symbol:   method key(), location: variable record of type java.lang.Object
            System.out.println(record.value()); //erro aqui  cannot find symbol, symbol:   method value(), location: variable record of type java.lang.Object
            System.out.println(record.partition()); //erro aqui  cannot find symbol, symbol:   method partition(), location: variable record of type java.lang.Object
            System.out.println(record.offset()); //erro aqui  cannot find symbol, symbol:   method offset(), location: variable record of type java.lang.Object
            try {
                Thread.sleep(5000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            System.out.println("Order Processed");
            System.out.println("###########################################");
}

Mas todas apresentaram o mesmo erro. Podem me ajudar?
