URL: https://github.com/apache/pulsar/issues/6929
**Describe the bug**
A clear and concise description of what the bug is.
Use KeyValue schema in Producer
Producer<KeyValue<Student, Student>> producer =
client.newProducer(
KeyValueSchema.of(Schema.JSON(Student.class),
Schema.JSON(Student.class)))
.topic("persistent://public/default/test-kvin2")
.producerName("producerTest").create();
Function code:
public class PulsarFunctionTest3 implements Function<KeyValue<Student,
Student>, KeyValue<Student, Student>> {
@Override
public KeyValue<Student, Student> process(KeyValue<Student, Student>
studentKeyValue, Context context) throws Exception {
context.getLogger().info("studentKeyValue key: {}",
studentKeyValue.getKey().toString());
context.getLogger().info("studentKeyValue: {}",
studentKeyValue.toString());
return studentKeyValue;
}
}
Pulsar Function log shows:
java.util.concurrent.CompletionException:
