The bulk API is not working

[nishantkshyp2004]

The Bulk python API is throwing the error:

es = Elasticsearch()
for line in request.FILES['document'].readlines():
            actions = [
                {
                    # "_op_type",
                    "_index": index_name,
                    "_type": index_type,
                    "_source": {
                        "utterance": line.decode('utf-8'),
                        }
                }]
            data.append(actions)
helpers.bulk(es, data)](url)```

This code is throwing the error:

The API is working fine.

The format of actions is dictionaries inside a list.

There is a bulk helper that greatly simplifies the format needed - http://elasticsearch-py.readthedocs.io/en/master/helpers.html#bulk-helpers

hope it helps
