"not_x_content_exception" while trying to PUT simple file with column mappings into ES via cURL

Elastic Stack Elasticsearch
1

Good day!

I'm a newbie in ELK and got stuck on the task that seemed to be a simple one on the first sight but that is not how it turned out.

What am I trying to do:
I have a table with test data in MS SQL Server and I want to setup data transfer from it via Logstash into Elasticsearch. I have successfully performed this task and data have reached the desired index in ES. The more we get the more we want. And I decided to setup explicit mappings for columns to make sure that data will be transferred from source table into ES index in desired format. To do this, I have created companies_list.mapping file with the following content:

{
    "companies_list": {
    "properties": {
        "id": {
            "index": "not_analyzed",
            "type": "string"
        },
        "number_of_employees": {
            "type": "long"
        },
        "name": {
            "index": "analyzed",
            "type": "string"
        },
        "description": {
            "index": "analyzed",
            "type": "string"
        },
        "homepage": {
            "index": "not_analyzed",
            "type": "string"
        },
        "location": {
            "geohash": true,
            "type": "geo_point"
        }
    }
  }
}

And trying to upload mappings from this file into ES using cURL. Sequence of my actions:

a. Delete all indicies in ES with command:

curl -X DELETE "http://localhost:9220/_all"

Result:

{"acknowledged":true}

b. Create index in ES:

curl -X PUT http://localhost:9220/companies_list

Result:

{"acknowledged":true}

c. Trying to PUT mappings from file:

curl -X PUT "http://localhost:9220/companies_list/_mapping/companies_list" -d "D:\ELK\mappings\companies_list.mapping"

Result:

{"error":{"root_cause":[{"type":"not_x_content_exception","reason":"Compressor detection can only be called on some xcontent bytes or compressed xcontent bytes"}],"type":"not_x_content_exception","reason":"Compressor detection can only be called on some xcontent bytes or compressed xcontent bytes"},"status":500}

I have googled this error but have not found the answer. Any suggestions on this?

You are missing the content type

Add -H 'Content-Type: application/json'

Thanks a lot for quick reply!
I have added this part into cURL command and now it looks like this:

curl -X PUT "http://localhost:9220/companies_list/_mapping/companies_list" -d "D:\ELK\mappings\companies_list.mapping" -H "Content-Type: application/json"

But it doesn't make sense. Still getting the same error.

what does companies_list.mapping look like?

Content of this file is provided in the first post. I have added filename and highlighted it there.

I think you need to use @ sign to reference a file in curl. Better to read curl manual. Should be something like

-d "@path/to/file"

Thanks!
@ sign in the start of the path has moved me to the next step! (name of some datatypes in the file). I think I will be able to resolve these new errors by myself.
So, the correct cURL command was:

curl -X PUT "http://localhost:9220/companies_list/_mapping/companies_list" -d "@D:\ELK\mappings\companies_list.mapping"

Better to use Kibana dev console. Much easier IMO.
