404 not found error using ServiceStack ServerEventsClient with Pipedream SSE API

I'm using Pipedream as a data source which provides event data via an SSE API.

As per the instructions here, I'm using the following code to subscribe to the SSE:

var client = new ServerEventsClient("https://api.pipedream.com/sources/dc_mXugEA/sse")
{
    EventStreamRequestFilter = req => req.AddBearerToken("[MYTOKEN]"),
    OnMessage = message => Console.WriteLine(message.Json)
}.Start();

However, I get a System.Net.WebException with the message 'The remote server returned an error: (404) Not Found.'

But if I use HttpClient directly, it succeeds:

var client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", "[MYTOKEN]");

using var reader = new StreamReader(await client.GetStreamAsync("https://api.pipedream.com/sources/dc_mXugEA/sse"));
while (!reader.EndOfStream)
{
    Console.WriteLine($"Received message: {await reader.ReadLineAsync()}");
}

Of course, I want to use ServerEventsClient instead of HttpClient to avoid the boilerplate looping code. But why is ServerEventsClient not working in this case?

ServiceStack’s Server Events clients only works with ServiceStack’s Server Events feature, I.e. it can’t be used to consume a 3rd Party SSE stream.
