Client.create error on elastic:5.0.0-rc1

A simple: client.create({ index: index_name, type: doc_type, timestamp: elem.date, body: elem },function (error_els, response) { [..] })

returns the following error is the post is done to Elastic:5.0.0-rc1: Validation Failed: 1: an id must be provided if version type or value are set

The condition in elastic that is being hit is the following: https://github.com/elastic/elasticsearch/blob/master/core/src/main/java/org/elasticsearch/action/index/IndexRequest.java if (id == null && (versionType == VersionType.INTERNAL && version == Versions.MATCH_ANY) == false) { validationException = addValidationError("an id must be provided if version type or value are set", validationException); }

My objective is to do a POST so that the id is automatically generated by elastic. The call works fine till elastic:5.0.0-alpha5

Just ran into this myself. I think the docs for create could use a link to the index method to clarify this behavior. I was used to the curl PUT and POST behavior and IMO create seemed to be the most idiomatic way to express creating a document/index (with or without an id).

Docs for create.
