Elasticsearch: Indexing document throws error "Invalid index name [_doc], must not start with '_'"

I created a new index a1.

curl -XGET "http://localhost:41349/_cat/indices?v"

health status index                                  uuid                   pri rep docs.count docs.deleted store.size pri.store.size
yellow open   a1                                     ba3S75mbSWyNdP2XYip8VA   5   1          0            0       810b           810b

When I try to index the document to a1 I get error.

curl -XPOST "http://localhost:41349/a1/_doc" -H "Content-Type:application/json" -d '{"dummy": "data"}'

{"error":{"root_cause":[{"type":"invalid_type_name_exception","reason":"Document mapping type name can't start with '_', found: [_doc]"}],"type":"invalid_type_name_exception","reason":"Document mapping type name can't start with '_', found: [_doc]"},"status":400}

I tried with PUT. This also failed.

curl -XPUT --header 'Content-Type: application/json' http://localhost:41349/_doc/1 -d '{ "school" : "Harvard" }'

No handler found for uri [/_doc/1] and method [PUT]

It seems that you are using Elasticsearch version below 7.x. The error clearly states that mapping type name cannot start with _

Document mapping type name can't start with '_'

You need to change your mapping type name (change from _doc to doc). Modify your curl request as

curl -XPOST "http://localhost:41349/a1/doc" -H "Content-Type:application/json" -d '{"dummy": "data"}'
