395 PointsNever mind I figured it out. The problem was in the Main.java file. Instead of doing this:
post("/sign-in", (req, res) -> {
Map<String, String> model = new HashMap<>();
model.put("username", req.queryParams("username") );
return new ModelAndView(model, "sign-in.hbs");
}, new HandlebarsTemplateEngine());
I had this:
post("/sign-in", (req, res) -> {
Map<String, String> model = new HashMap<>();
model.put("username", req.queryParams("username") );
return new ModelAndView(null, "sign-in.hbs");
}, new HandlebarsTemplateEngine());
