[Bug] Items are not created

I have Zabbix 3.4.12 and Prometheus 2.7.1 and can't get items and triggers created in Zabbix. Configuration:

$ kubectl exec -it prometheus-zabbix-webhook-78fc67bffc-6xr8p -c alertmanager-zabbix-provisioner -- /bin/sh -c 'cat /etc/provisioner/config.yaml'
# URL to the Status/Rules page
rulesUrl: http://prometheus-operator-prometheus.monitoring.svc.cluster.local:9090/rules

# Polling interval in seconds
rulesPollingInterval: 3600

# Full URL to your Zabbix API
zabbixApiUrl: https://zabbix.some.host/zabbix/api_jsonrpc.php

# Zabbix items key prefix, keys will be zabbixKeyPrefix.alertname
zabbixKeyPrefix: prometheus

# List of host configuration
zabbixHosts:
  # Name of the host in zabbix
  - name: gmauleon-test01
    selector:
      zabbix: gmauleon-test01
    hostGroups:
      - some_group
    itemDefaultApplication: prometheus

logs:

Configuration for alert in Prometheus:

- alert: KubeStatefulSetReplicasMismatch
  annotations:
    zabbix: gmauleon-test01
    message: StatefulSet {{`{{ $labels.namespace }}`}}/{{`{{ $labels.statefulset }}`}} has not matched the expected number of replicas for longer than 15 minutes.
    runbook_url: https://github.com/kubernetes-monitoring/kubernetes-mixin/tree/master/runbook.md#alert-name-kubestatefulsetreplicasmismatch
  expr: |-
    kube_statefulset_status_replicas_ready{job="kube-state-metrics"}
      !=
    kube_statefulset_status_replicas{job="kube-state-metrics"}
  for: 15m
  labels:
    severity: critical

I do see this alert at prometheus:9090/rules page:

What I expect to see Host gmauleon-test01 in Zabbix at least one item and trigger for KubeStatefulSetReplicasMismatch alert.

What I see Host gmauleon-test01 in Zabbix with no items or triggers.

Sidenotes Debug logging could help to find out what is the problem, but it's hardcoded into application - no way to configure it via yaml.
