Question about routing path parameters:

Suppose I have a route: get("/foo/{param1}/bar" { ... }

When I access call.parameters["param1"] the type is String?. My question is, can this ever actually be null? What situation would lead to a request with no value for param1 being routed to that handler?

(I am avoiding the Locations feature for now since it is marked experimental.)

it's probably just because the parameters can't be checked at compile time, you could do call.parameters["foo"] without having {foo} anywhere in your route (although it could throw an exception in that case instead of returning a nullable)

Good point.
