putScript: request [/_scripts/candidate-score] contains unrecognized parameter: [lang]

• OS: Mac 10.14.3
• npm: 6.4.1
• node: 10.15.0
• elasticsearch client: 15.4.1
• typescript: 3.3.3333
• @types/elasticsearch: 5.0.32

When calling putScript, I’m getting this error: request [/_scripts/candidate-score] contains unrecognized parameter: [lang]. Looks like the lang parameter is being set as a querystring parameter. I get the same response when replicating the call in Kibana. When calling the same request in Kibana without the querystring, getting successful response:

{
  "acknowledged": true
}

Call/Logs/Responses

	// Calling elasticsearch client
	this.client.putScript({
		id,
		lang,
		body: {
			script: {
				lang,
 				source
			}
		}
	})

    /* 
		DEBUG LOG
			starting request {"method":"PUT","path":"/_scripts/candidate-score",
			"body":{"script":{"lang":"painless","source":"REDACTED"}},
			"query":{"lang":"painless"}}
    */

What may be causing this issue?

Here is the submitted bug: https://github.com/DefinitelyTyped/DefinitelyTyped/issues/34513. I will close issue, thanks for your help @spalger!

Ignoring the typescript rule does the trick in getting the putScript method to run without lang. I will submit a bug in the @types/elasticsearch package definition and will post the issue in this thread.
