Iceberg Connector Confluent: java.lang.ClassNotFoundException: org.apache.iceberg.IcebergBuild

[santurini]

I am deploying a confluent stack in Kubernetes which install the Apache Iceberg Connector like this:

apiVersion: platform.confluent.io/v1beta1
kind: Connect
metadata:
  name: connect
  namespace: confluent
spec:
  replicas: 1
  image:
    application: confluentinc/cp-server-connect:7.9.0
    init: confluentinc/confluent-init-container:2.11.0
  build:
    type: onDemand
    onDemand:
      plugins:
        confluentHub:
          - name: debezium-connector-mysql
            owner: debezium
            version: latest
          - name: iceberg-kafka-connect
            owner: iceberg
            version: latest

But as soon as I create a sink connector, I have this error trace:
