i don't know where is the problem

The problem is here:

406, 'Content-Type header  is not supported'

You need to provide the application/json content type.
See https://www.elastic.co/fr/blog/strict-content-type-checking-for-elasticsearch-rest-requests

[idris]

as just you said ,my mapping contains application/json content type.But,it doesn't work.

curl -X PUT "localhost:9200/newsout/_mapping/test-type" -H '
Content-Type: application/json' -d' {

"properties": {
    "author": { "type": "keyword"  },
    "date": {
        "type": "date",
        "format": "yyyy-MM-dd"
    },
    "description": {
        "type": "text",
        "analyzer": "french"
    },
    "topics": { "type": "keyword"  },
    "link": { "type": "text", "index": "true"  },
    "locations": { "type": "keyword"  },
    "organizations": { "type": "keyword"  },
    "persons": { "type": "keyword"  },
    "text": {
        "type": "text",
        "analyzer": "french"
    },
    "title": {
        "type": "text",
        "analyzer": "french"
    }
}

}'

the output is

{"acknowledged":true}

it seems that is the same error

iraise HTTP_EXCEPTIONS.get(status_code, TransportError)(status_code, error_message, additional_info)
elasticsearch.exceptions.TransportError: TransportError(406, 'Content-Type header [] is not supported')

i m confused i don't understand this problem !!!!

[dadoonet (David Pilato)]

The problem is most likely in the Python code I guess. You wrote this code right?

[idris]

yes i wrote a part of this code , but ,i think maybe there is a problem with request or http_urllib3

[dadoonet (David Pilato)]

What does your code look like? Not sure I can help though as I'm not a Python dev but I'm sure others could help.

[idris]

thank you ,it s okay i fixed the problem

[dadoonet (David Pilato)]

Would be great to share your solution for the next readers.

[idris]

i ve just removed the wrong version for ulrlib3 and requests library python .

I retry to download them and it works.
