Separate labels from message in loki

[freedomwarrior]

Hello.
I deploy vector using helm chart with this config:

customConfig:
  data_dir: /vector-data-dir
  sources:
    k8s:
      type: kubernetes_logs
  sinks:
    loki:
      type: loki
      compression: snappy
      encoding:
        codec: json
      inputs: [k8s]
      endpoint: http://loki-gateway.default.svc.dev.k8s.local
      path: /loki/api/v1/push
      out_of_order_action: accept
      remove_timestamp: false
      remove_label_fields: true
      labels:
        forwarder: "vector"

And the problem is that all labels comes as regualar text, and message looks like that:

Message value and labels are mixed and I need to separate them.
