elasticsearch update gives unknown field error

Question

I am using the Elasticsearch's Typescript client, and when I try to update a document:

import { RequestParams } from '@elastic/elasticsearch'      
const updateParam: RequestParams.Update = {
      id: '111',
      index: 'myIndex',
      body: {email: '[email protected]'},
}
return elasticsearchClient.update(updateParam)

I am getting an error saying:

{
    "error": {
        "root_cause": [
            {
                "type": "x_content_parse_exception",
                "reason": "[1:2] [UpdateRequest] unknown field [id], parser not found"
            }
        ],
        "type": "x_content_parse_exception",
        "reason": "[1:2] [UpdateRequest] unknown field [id], parser not found"
    },
    "status": 400
}

But according to the document here: https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/api-reference.html#_update, id is a field in the input

What's wrong with my request param?

Answer 1

Turned out, the RequestParams.Update should looke like this:

const updateParam: RequestParams.Update = {
      id: '111',
      index: 'myIndex',
      body: {doc:{email: '[email protected]'}},
}

So the actual data will need to be wrapped in "doc" field. I will make a PR to the lib on github... there is no way people can just figure it out by just the documentation.

Answer 2

Send the body in "doc" key to resolve this problem. I am using typescript along with Elasticsearch 7.8. Earlier it was 6.7 version where found no issues but started getting it after migration to newer version.

Answer 3

This 'id' is not a field in your document content.It just like 'index' and 'type'.You can't change index's name and type when you update one document,so you can't change one document's id.It is the identification of a document.But if you have a field named 'id',you can update like that.
