Elasticsearch 8 output - Error code 400 - unknown parameter [ _type ]

https://www.elastic.co/guide/en/elasticsearch/reference/7.17/removal-of-types.html Elasticsearch drop mapping types

Now, when I try send logs to elasticsearch, I got an error:

{ "error": { "root_cause": [ { "type": "illegal_argument_exception", "reason": "Action/metadata line [1] contains an unknown parameter [_type]" } ], "type": "illegal_argument_exception", "reason": "Action/metadata line [1] contains an unknown parameter [_type]" }, "status": 400 }

How I can override this?

Not sure if it's a good fix (probably not backwards compatible), but this seems to work:

     if (elasticsearchDocId !== null) {

     }

     this.bulkReq.write(stringifySafe(msg) + '\n')
