Python Elasticsearch 7.05 indexing failing - python-3.x

Question

I have created an index on my ES server via Kibana that looks like this
PUT export_control
{
"mappings": {
"properties": {
"content": {
"type": "text",
"term_vector": "with_positions_offsets"
}
}
}
}
Result is
{
"acknowledged" : true,
"shards_acknowledged" : true,
"index" : "export_control"
}
When I try to index a new document with the following command in python
col_names = df.columns
for row_number in range(df.shape[0]):
body = dict([(name, str(df.iloc[row_number][name])) for name in col_names])
es.index(index = 'export_control', doc_type="pdf_document", body = body)
I get the following error
RequestError Traceback (most recent call last)

2 for row_number in range(df.shape[0]):
3 body = dict([(name, str(df.iloc[row_number][name])) for name in col_names])

Answer 1

The problem is that in Elasticsearch types were removed recently - some full definition of it, which means, that you could have only one type - called _doc, while you're creating second one - pdf_document.
You should use
es.index(index = 'export_control', doc_type="_doc", body = body)
