Adding a DefaultParameter on a RestClient and use it in a Post request doesn't work

[giembultje]

Describe the bug
Adding a DefaultParameter on a RestClient and use it in a Post request doesn't work anymore in version 108.0.2. The parameter is ignored and not send in the request. This did work in version 106.

To Reproduce
Create a restclient and when created add a default parameter:

private RestClient CurrentRestClient { get; set; } = null;

CurrentRestClient = new RestClient("myrestendpoint");
CurrentRestClient.AddDefaultParameter("f", "json");

RestRequest myrequest= new RestRequest("mypath", Method.Post);
RestResponse response = CurrentRestClient.Execute(myrequest);

Response contains a HTML output because the server did not receive the f parameter.
When adding the next line, the response is correct:

myrequest.AddParameter("f", "json");

So adding the parameter on the request works fine.

Expected behavior
When adding a default parameter as get/post, the parameter should also be sent to the server in case of a post request.

Desktop (please complete the following information):

• OS: Windows
• .NET version 6
• Version 108.0.2

I've created a workaround:

private RestResponse ExecuteWithDefaults(RestRequest request)
{
	foreach (Parameter parameter in CurrentRestClient.DefaultParameters)
	{
		request.AddParameter(parameter);
	}
	return CurrentRestClient.Execute(request, Method.Post);
}
