Hi,

I recently performed the first upgrade of Logstash from version 8.10.4 to 8.12.1 and encountered an error during the process. It's important to note that this error only occurs during the initial upgrade and not during the installation process.

```auto

```

**Versions:**

- Logstash: 8.12.1
- OpenSearch: 2.11.0

This error doesn't come up on installation or further upgrades.

```auto
{"cluster_name":"test","status":"yellow","timed_out":false,"number_of_nodes":3,"number_of_data_nodes":1,"discovered_master":true,"discovered_cluster_manager":true,"active_primary_shards":3,"active_shards":3,"relocating_shards":0,"initializing_shards":0,"unassigned_shards":1,"delayed_unassigned_shards":0,"number_of_pending_tasks":0,"number_of_in_flight_fetch":0,"task_max_waiting_in_queue_millis":0,"active_shards_percent_as_number":75.0}

```

```auto
curl -k -u<user>:<password> "http://localhost:9200/_cluster/health"
{
  "name" : "test",
  "cluster_name" : "test",
  "version" : {
    "number" : "7.10.2",
    "build_type" : "rpm",
    "build_snapshot" : false,
    "lucene_version" : "9.7.0",
    "minimum_wire_compatibility_version" : "7.10.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "The OpenSearch Project: https://opensearch.org/"
}

```

Query:

- Has anyone else experienced a similar issue during their first upgrade from Logstash 8.10.4 to 8.12.1?
- Are there any specific steps or configurations recommended for handling the first upgrade process?
- Could there be a compatibility issue between Logstash 8.12.1 and OpenSearch 2.11.0 that manifests uniquely during the initial upgrade?

Any guidance or insights on resolving this issue would be greatly appreciated.

Thank you!

OpenSearch/OpenDistro are AWS run products and differ from the original Elasticsearch and Kibana products that Elastic builds and maintains. You may need to contact them directly for further assistance.

I think you need to ask the authors of this output plugin as we are not developing it.
