I'm trying to create an Ingest Pipeline in Elasticsearch 7.4 that will allow me to to take the value of the "\_id" metadata field and copy it into a new field. I've tried using the "set" processor to do this, but I'm unable to do so. Below is the ingest pipeline settings

```auto
PUT _ingest/pipeline/<pipeline name>
{
"description": "Move value from _id metadata field to new_field",
"processors": [
{
    "set": {
         "field": "new_field",
         "value": "{{_id}}"
}
}
]
}

}

```

Can you try using `"value": "{{{_id}}}"`?

To access field values you need to use triple curly brackets. [[documentation](https://www.elastic.co/guide/en/elasticsearch/reference/7.14/ingest.html#access-metadata-fields)]
