Hello,

Now, I'm using Amazon Elasticsearch Service with High Level Rest Client.

Firstable, I tried to create snapshot with `CreateSnapshotRequest`.

This trial has request body (following code block) according to http log.

```json
{
  "repository": "snapshot-repository-name",
  "snapshot": "snapshot-name",
  "indices": [
		// names of indices
  ],
  "partial": false,
  "settings": {},
  "include_global_state": true,
  "expand_wildcards": [
    "open"
  ],
  "ignore_unavailable": false,
  "allow_no_indices": true,
  "ignore_throttled": false
}

```

but response i'd got was :

```auto
{
    "Message":"settings.role_arn is needed for snapshot registration."
}

```

I thought this message is given when **create snapshot repository.**

So, I tried with Low Level Rest Client.

I build request body using json string by referring to [elastic search documentation](https://www.elastic.co/guide/en/elasticsearch/reference/7.1/modules-snapshots.html#_snapshot)

Then, request was successful and snapshot was created.

Finally, I realized the problem is from `settings` property of `CreateSnapshotRequest` .

According to `CreateSnapshotRequest#toXContent`, if `settings` is null, json builder would not contain `settings`. This looks like `settings` can be `null`. But `CreateSnapshotRequest#validate` show me could not set `settings` null.

Then, how can I request without `settings` using CreateSnapshotRequest ?

I do not see this message anywhere in the source code. If you're using the AWS Elasticsearch Service then you are running a nonstandard version of Elasticsearch with a number of proprietary modifications to which we do not have access. I suspect this incompatibility is coming from such a modification. You'll need to contact Amazon about that, or you can set up a hosted cluster running the official version at [Elastic Cloud: Hosted Elasticsearch, Hosted Search | Elastic](https://www.elastic.co/cloud/).
