FastEndpoints PATCH with route param, headers and no body

What im trying to do is send a PATCH call to an endpoint which has route params but also required headers and no body.

public class TestRequest
{
    [FromHeader("x-correlation-id")]
    public Guid CorrelationId { get; set; }
    [BindFrom("EntityId")]
    public Guid EntityId { get; set; }
}

public sealed class TestEndpoint : Endpoint<TestRequest>
{
    public override void Configure()
    {
        Patch("{EntityId}/fulfill");
    }

    public override async Task HandleAsync(TestRequest req, CancellationToken cancellationToken)
    {
        await SendOkAsync(cancellationToken);
    }
}

The above displays the 2 properties in Swagger UI but when i call it i get 415 Unsupported Media Type which as i understand is returned because the FastEndpoints Endpoint<T> sends a body even though its empty. I can verify this if i manually send the properties as the route param and header accordingly and set the Content-type: application/json header which in turn returns a JsonSerializer error because the body is null and not in a json format.

I have also tried with EndpointWithoutRequest but this does not take any model as a request therefore the CorrelationId prop cannot be set and i cannot find any way to set it in the endpoint.

What i would like to find is a way to display all the header properties and the route params in SwaggerUi and be able to send a simple curl with

curl -X 'PATCH' \
  '.../72423509-c29b-4735-862a-9ebdd0489c05/fulfill' \
  -H 'x-correlation-id: 72423509-c29b-4735-862a-9ebdd0489c05'

You'd have to clear the default accepts metadata

public override void Configure()
{
    Description(x => x.Accepts<ToggleSettingRequest>());
}
