Decode_json_fields not

[Areeb_Siddiqui]

I am using filebeat on kubernetes. My filebeat.yaml looks like this:

filebeat.autodiscover:
  providers:
    - type: kubernetes
      node: ${NODE_NAME}
      templates:
      - condition:
          equals:
            kubernetes.labels.app: app-name
        config:
          - type: container
            paths:
            - /var/log/containers/*${data.kubernetes.container.id}.log
            processors:
              - decode_json_fields:
                  fields: ["message"]
                  process_array: true
                  max_depth: 1
                  target: "Message"
                  overwrite_keys: false
                  add_error_key: true

However on my kibana dashboard in Mesasge Coloum I am having logs like this:

{
  "log.level": "info",
  "@timestamp": "2023-12-14T11:59:24.638Z",
  "log.origin": {
    "file.name": "filename",
    "file.line": 270
  },
  "message": "Received Request",
  "trace.id": "xxx",
  "transaction.id": "xxx",
  "user.name": "username",
  "ecs.version": "1.6.0"
}

But I want something like this

[Info] "Received Request"

How can I achieve this?

Note: The log file contains the log in the following format on k8s node.

directory: /var/log/containers/*${data.kubernetes.container.id}.log

2023-12-14T12: 13: 59.872959737Z stdout F {
{
  "log.level": "info",
  "@timestamp": "2023-12-14T11:59:24.638Z",
  "log.origin": {

    "file.line": 270
  },
  "message": "Received Request",
  "trace.id": "xxx",
  "transaction.id": "xxx",
  "user.name": "username",
  "ecs.version": "1.6.0"
}
