Curl XPOST errors not supported 406

I have installed elasticsearch 7.6.1 on an AWS EC2 instance.
When I give the following curl command from Windows I get a valid JSON response:
curl -XGET "http://<EC2-IP>:9200"
However when I give the following command:
curl -XPOST "http://<EC2-IP>:9200/table_search_index/_doc/<doc_id>" -H 'Content-Type: application/json' -d'{<json_doc>}'
I get the error:
{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}

Can anyone tell me what the issue would be?

you're missing the correct content-type header. As an example, go to the documentation at and click the copy as cUrl button, you will see how to add the proper header to your curl calls.

Thanks for the link.
I checked the header generated when I clicked on the copy as cUrl button.
The header generated by it was -H 'Content-Type: application/json' which is the same header I have mentioned in the command I gave to POST my data.
So is there any other reason for the failure?

Given the response I dont think that the option has been passed to curl or properly parsed.

Can you put the output of curl -v into a pastebin, this will allow you see check the headers from the request that is sent to elasticsearch?
