Hi,

We have been using node stats API (`pipelines` end point) to monitor health of our multiple logstash pipelines.

After we have upgraded from 8.16.1 to 8.17.3, the endpoint is returning `pipelines: {}` despite pipelines running correctly.

```auto
curl -XGET 'http://localhost:9600/_node/stats/pipelines?pretty'
{
  "host" : "logstash2",
  "version" : "8.17.3",
  "http_address" : "127.0.0.1:9600",
  "id" : "xxx",
  "name" : "logstash2",
  "ephemeral_id" : "xxx",
  "snapshot" : false,
  "status" : "green",
  "pipeline" : {
    "workers" : 7,
    "batch_size" : 2000,
    "batch_delay" : 50
  },
  "monitoring" : {
    "hosts" : ["esdatanodes"],
    "username" : "logstash_system"
  },
  "pipelines" : { }
}

```

Querying individual pipelines using the id gives correct results

```auto
curl -XGET 'http://localhost:9600/_node/stats/pipelines/mypipelineid?pretty' 
{
  "host" : "logstash2",
  "version" : "8.17.3",
  "http_address" : "127.0.0.1:9600",
  "id" : "xxx",
  "name" : "logstash2",
  "ephemeral_id" : "xxx",
  "snapshot" : false,
  "status" : "green",
  "pipeline" : {
    "workers" : 7,
    "batch_size" : 2000,
    "batch_delay" : 50
  },
  "monitoring" : {
    "hosts" : ["esdatanodes"],
    "username" : "logstash_system"
  },
  "pipelines" : {
    "mypipelineid" : {
      "events" : {
        "in" : 1724233,
        "queue_push_duration_in_millis" : 181443,
        "filtered" : 1719141,
        "out" : 1719146,
        "duration_in_millis" : 1151370
      },
      "flow" : {
        "queue_backpressure" : {
          "current" : 0.1667,
          "last_1_minute" : 0.1645,
          "last_5_minutes" : 0.1633,
          "lifetime" : 0.3642
        },
...

```

Has anyone encountered something similar? Do we need to change some logstash setting after upgrade or is this a bug?

This was a [bug](https://github.com/elastic/logstash/issues/17180) that has been fixed (and probably rolled out in next version) but I can't update to 8.17.4 due to known http-poller issue with that version.
