I'm trying to hit my restful service with a request
(org.bowlerframework / core_2.9.1 / 0.5) and getting the error as
below.

I don't want to do any templating at this point; what is the minimum
set of things I need to do to get an http request processing roundtrip
going?

All I'm doing is basically this

class MyController extends Controller with
FunctionNameConventionRoutes with Renderable {

def `GET /hello` = render("Hello, world")

The error is as follows

java.lang.Exception: '<html>
<head>
<meta http-equiv="Content-Type" content="text/html;
charset=ISO-8859-1"/>
<title>Error 500 Could not find a template of

Hi,

The render method will automatically try to negotiate the right content-type for you based on your clients Accept http header.

If it decides that the content should not be application/json it will by default try to look up a template from your classpath.

However if you just wish to render "Hello world" without getting a template, it is better to just do:
