Get field mapping API with nested field

Elastic Stack Elasticsearch
1

Hi everyone!

I am using the Get field mapping API to check if a field exists in Elasticsearch.

My index is:

"mappings": {
    "dynamic": "strict",
    "properties": {
        "_customer": {
            "type": "nested",
            "properties": {
                "_name": {
                    "type": "text"
                },
                "_types": {
                    "type": "nested",
                    "properties": {
                        "_description": {
                            "type": "text"
                        },
                        "_items": {
                            "type": "nested"
                        }
                    }
                }
            }
        },
        "id": {
            "type": "keyword"
        }
    }
}

And I run the GET request:

/myIndex/_mapping/field/_customer._types._items?allow_no_indices=false

But the response has not my field:

{
    "myIndex": {
        "mappings": {}
    }
}

The response should not have the mapping of my field? This is bug or am I doing something wrong?
