Help with using dynamic template

Elastic Search
1

I get the following error when using dynamic_templates, I'd like to map the fields with k8s.* as text and nested object field "network" as a flat_object.
I've tried using both regex and path_match but get the same error.

Can anyone let me know if I'm doing it correctly?

Configuration:

PUT _index_template/test_logs
{
  "index_patterns": [
    "test_*"
  ],
  "template": {
    "mappings": {
      "dynamic_templates": [
        {
          "k8s_fields_as_text": {
            "match_pattern": "regex",
            "match": "^k8s.*",
            "mapping": {
              "type": "text"
            }
          }
        },
        {
          "nested_object_fields_as_flat_object": {
            "match": "*",
            "match_mapping_type": "object",
            "mapping": {
              "type": "flat_object"
            }
          }
        }        
      ]   
    }
  }
}

PUT test_logs/_doc/1
{
  "k8s.application.name": "test-app",
  "k8s.container.restart_count": "0",  
  "k8s.namespace.name": "test",
  "k8s.pod.name": "test-app-9f45bf4b-v76fr",
  "network": {
    "ip_address": "10.10.1.15", 
    "security_group_id": "sg-111111111111111", 
    "subnet_id": "subnet-111111111111111",
    "vpc_id": "vpc-111111111111111"
  }
}

Error:

{
  "error": {
    "root_cause": [
      {
        "type": "class_cast_exception",
        "reason": "class_cast_exception: class org.opensearch.index.mapper.TextFieldMapper cannot be cast to class org.opensearch.index.mapper.ObjectMapper (org.opensearch.index.mapper.TextFieldMapper and org.opensearch.index.mapper.ObjectMapper are in unnamed module of loader 'app')"
      }
    ],
    "type": "mapper_parsing_exception",
    "reason": "failed to parse",
    "caused_by": {
      "type": "class_cast_exception",
      "reason": "class_cast_exception: class org.opensearch.index.mapper.TextFieldMapper cannot be cast to class org.opensearch.index.mapper.ObjectMapper (org.opensearch.index.mapper.TextFieldMapper and org.opensearch.index.mapper.ObjectMapper are in unnamed module of loader 'app')"
    }
  },
  "status": 400
}

Note: I'm using OpenSearch 2.11 and they don't have documentation on dynamic_templates hence I've raised a topic here.

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.

Opensearch is not supported here, you will need to direct this question to an Opensearch forum.
