spring-projects/spring-kafka

Hi @garyrussell and team, please I need help I am a newbie in this space, and I have an issue getting my configuration right, I am trying to send the same message to different Kafka-topic for different consumers to consume.
but I am not getting any messages at the consumer end, while the producer is sending the message successfully. I guess it's from my application.yml file where I have the config setup.

This is the Producer config

spring:
  data:
    mongodb:
      authentication-database: admin
      user: ${mongodb_user}
      password: ${mongodb_password}
      host: localhost
      port: 27017
      database: orderServiceDB

  application:
    name: OrderService

  stream:
    kafka:
      binder:
        brokers: ${KAFKA_HOST:localhost}:${KAFKA_PORT:9092}
        auto-add-partitions: true
        min-partition-count: 2
    bindings:
      orderApproval-in-0:
        destination: vendorServiceTopic, paymentService
        content-type: application/*+avro
        group: vendorServiceGroup
        consumer:
          max-attempts: 4
          back-off-initial-interval: 10000
      sendOrder-out-0:
        destination: orderServiceTopic
        content-type: application/*+avro
        producer:
          partitioned: true
          partition-key-expression: headers['partitionKey']
          partition-count: 2

    zipkin:
      base-url: http://localhost:9411/
    sleuth:
      sampler:
        probability: 1

And these are the Consumers

spring:
  data:
    mongodb:
      authentication-database: admin
      user: ${mongodb_user}
      password: ${mongodb_password}
      host: localhost
      port: 27017
      database: productServiceDB
  cloud:
    schema-registry-client:
      endpoint: http://${SCHEMA_REGISTRY_HOST:localhost}:${SCHEMA_REGISTRY_PORT:8081}
    stream:
      kafka:
        binder:
          brokers: ${KAFKA_HOST:localhost}:${KAFKA_PORT:9092}
          auto-add-partitions: true
      bindings:
        sendOrder-in-0:
          destination: orderEvent
          content-type: application/*+avro
          group: orderServiceGroup
          consumer:
            instanceCount: 2
            instanceIndex: 2
            max-attempts: 4
            back-off-initial-interval: 10000

spring:
  data:
    mongodb:
      authentication-database: admin
      user: ${mongodb_user}
      password: ${mongodb_password}
      host: localhost
      port: 27017
      database: customerServiceDB

  application:
    name: CustomerService
  cloud:
    schema-registry-client:
      endpoint: http://${SCHEMA_REGISTRY_HOST:localhost}:${SCHEMA_REGISTRY_PORT:8081}
    stream:
      kafka:
        binder:
          brokers: ${KAFKA_HOST:localhost}:${KAFKA_PORT:9092}
          auto-add-partitions: true
      bindings:
        customerService-in-0:
          destination: customerOrderEvent
          content-type: application/*+avro
          group: orderServiceGroup
          consumer:
            max-attempts: 4
            back-off-initial-interval: 10000

  zipkin:
    base-url: http://localhost:9411/

when I run the code I get the following but I am still confused, can someone explain to me like a baby

partitions assigned: [customerOrderEvent-in-0-0]

partitions assigned: [orderEvent-in-0-0]
thanks
