So I went ahead and wrote a simple client by hand and when I call the two functions on a local endpoint that shows me the request URL I get the following.<br class="gmail_msg">

I haven't used swagger-codegen but the servant-client code works for me so I would look more into that.<br class="gmail_msg">
<br class="gmail_msg">
Swagger codegen looks like it might take me a while to get my head into so maybe you could look at the generated code, or sling it to me here or directly.<br class="gmail_msg">
<br class="gmail_msg">
The two calls are so similar that I can't see why the generated client would behave differently in those cases.<br class="gmail_msg">

It would be really useful to see exactly how you are 'calling' this.<br class="gmail_msg">

Do you have a curl command line or are you using some other client?<br class="gmail_msg">
