Trying to get restsharp to match curl code from postman

Question

This has been asked a hundred times, but none of them seem to work for me. I have the following curl code:

curl --location --request POST 'https://endpoint/telemetry' \
--header 'x-ads-dev: akeyvalue' \
--header 'Content-Type: application/json' \
--data-raw '[
    {
        "entityID": 2123,
        "locationID": 33,
        "dataPoints": [
            {
                "dateTime": "2020-08-03 23:05:00",
                "reading": 0,
                "flags": 0,
                "quality": 0,
                "ignore": true
            },
            {
                "dateTime": "2020-09-27 03:10:00",
                "reading": 0,
                "flags": 0,
                "quality": 0,
                "ignore": true
            }
        ]
    }
]'

When I run this in postman I get a different response from the server than when I try to work it into restsharp. Here is my rest sharp code:

try {
    string url = "https://endpoint/";
    var client = new RestClient(url);
    client.AddDefaultHeader("x-ads-dev", "akeyvalue");
    var request = new RestRequest("telemetry", Method.Post);
    request.AddHeader("Content-Type", "application/json");
    request.AddParameter("application/json", datapoint, ParameterType.RequestBody);
    var response =  await client.PostAsync(request);

The value of the variable datapoint is:

[
   {
      "entityID":2123,
      "locationID":33,
      "dataPoints":[
         {
            "dateTime":"2020-08-03 23:05:00",
            "reading":0,
            "flags":0,
            "quality":0,
            "ignore":true
         },
         {
            "dateTime":"2020-09-27 03:10:00",
            "reading":0,
            "flags":0,
            "quality":0,
            "ignore":true
         }
      ]
   }
]

When I run it through postman with the curl code the server accepts the request, but when I run it through restsharp I get bad request error.

EDITED the code to match the below comment, as doing so didn't solve my problem.

I'm pretty sure the content type you define using the AddParameter is the culprit. Have you tested it like so:

request.AddParameter("application/json", datapoint, ParameterType.RequestBody);

or using AddJsonBody

request.AddJsonBody(datapoint);
