Bulk updating without type using elastic search py

Question

I'm trying to do a bulk insert using elastic search py, but I don't want to specify a type, but it won't allow me to specify None or "" for the value of type. How can I get around this?

bulk_data = []

this_merchant_product = {'field1': 'value1'}

op_dict = {
    "index": {
        "_index": "product",
        "_type": None,
        "_id": str(this_merchant_product_id)
    }
}

bulk_data.append(op_dict)
bulk_data.append(this_merchant_product)

es = Elasticsearch()
res = es.bulk(index='product', body=bulk_data)

I've also tried to set _type to "", but that doesn't work either.

These are the error messages.

This is the error when I set _type to None:

elasticsearch.exceptions.RequestError: RequestError(400, 'action_request_validation_exception', 'Validation Failed: 1: type is missing;

and this is the error I get when I set _type to "":

java.lang.IllegalArgumentException: name cannot be empty string

Each index has one mapping type in Elasticsearch 6.x+. In Elasticsearch 7.x+ type is removed. In version 2.x - 5.6 you could have used more then one mapping. Assuming that you’re using version 6.x, you need to have type of documents in index.

Gotcha. It looks like the default type is "_doc" if you use elasticsearch-py, in case anyone finds that useful in the future. That's the only value for type that doesn't give me an error.
