i'm deploying telegraf to kubernetes , the goal is to consume kafka messages from a kafka topic and send this message to zabbix as a persistent storage , the telegraf input plugin kafka consumer is working fine and messages are being comsumed but it's not appearing in zabbix here is my code :

apiVersion: v1
kind: ConfigMap
metadata:
  name: telegraf-config
  namespace: zabbix-dev-ns
data:
  telegraf.conf: |
    [agent]
      debug = true
      quiet = false
      metric_buffer_limit = 1000000
      hostname = "telegraf-kafka-host"

    [[inputs.kafka_consumer]]
      brokers = ["kafka:9093"]
      topics = ["zabbix-auditlog-dev2"]

      tls_ca = "/opt/sbd_root_ca.crt"
      tls_cert = "/opt/auditlog-zabbix.crt"
      tls_key = "/opt/auditlog-zabbix.key"

      consumer_group = "zabbix-auditlog-dev2"
      offset = "oldest"
      data_format = "json"
      json_string_fields = ["zabbix_instance","auditid","userid","action",
       "resourcetype","details","ip","resourceid","resourcename"]
    [[outputs.file]]
      files = ["stdout"]
      data_format = "json"

    [[outputs.prometheus_client]]
      listen = ":9273"
      path = "/metrics"
      

    [[outputs.zabbix]]
      address = "zabbix-server-dev2-k-a.zabbix-dev-ns.svc.cluster.local:10051"
      key_prefix = "telegraf."
      lld_send_interval = "30s"
      lld_clear_interval = "1h"
      skip_measurement_prefix = true
      agent_active = false

the logs looks like this and i created a host in zabbix with an item with key telegraf.fields but nothing showing here
