How to have .AddJsonBody ignore nulls in object in C# utilizing RestSharp

Question

I'm having issues with getting my JsonBody to parse without the null fields so I just perform updates on fields I want within the object. I know I can get around this by just passing the values I want as a new object but was trying to have it accept whichever values weren't set to null in the object only.

var request = new RestRequest($"/example", Method.Patch)
            .AddJsonBody(object);
        

var response = await restClient.ExecuteAsync(request);

Attempted to add the below when I was creating my RestClient but it didn't the s.UseSystemTextJson portion for me to be able to add the JsonSerializerOptions

var client = new RestClient(
    options, 
    configureSerialization: s => s.UseSystemTextJson(new JsonSerializerOptions {...})
);

Also, attempted to add [JsonObject(ItemNullValueHandling = NullValueHandling.Ignore)] to the object

Try this :

var jsonOptions = new JsonSerializerOptions
{
  IgnoreNullValues = true
};

It will exclude null values from the JSON.

Pass it to the Serialize()

var json = JsonSerializer.Serialize(object, jsonOptions);

Create request like :

var request = new RestRequest($"/example", Method.Patch)
        .AddParameter("application/json", json, ParameterType.RequestBody);
