Hi, I'm trying to put some data into my elastic cloud instance using Postman.  
I set the headers to be 'Content-Type' - 'application/json', and the body is a valid json object.  
I am trying to do a PUT request to a new index, how ever I get this error:

```
{
    "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
}

```

Any idea what might be causing it?

Can you share the `PUT` request that yields this error?
