Clojurians Log v2

@hlship, I'm seeing this too in 0.8.0-beta2. I'm taking a stab a moving over to connectors. It seems to be related to resources. I've moved to using resource-routes which eventually results in a call to https://github.com/pedestal/pedestal/blob/0.8.0-beta-2/service/src/io/pedestal/service/resources/impl.clj#L34 but... the appropriate https://github.com/pedestal/pedestal/blob/0.8.0-beta-2/servlet/src/io/pedestal/http.clj#L56C1-L61C32 is in the deprecated io.pedestal.http which I no longer want to :require because of the deprecation. If you need a reproduction/issue lemme know.

Sorry yes this happens during execution of requests. Here is context (some values omitted) + stacktrace:

I suspect if you change your code to, somewhere, require io.pedestal.http.jetty.container, it will all work. Because you are going through the FnServlet, and not configuring Jetty directly, this namespace (which maps Jetty classes to Pedestal protocols) is never loaded.

It would be helpful to see any web.xml configuration, and what your startup code looks like.

This is great, exactly the kind of things I want to flesh out during a beta!

Want a git issue for it? Or all good?

Sure, let’s move the conversation to a Pedestal issue.

Here ya go: https://github.com/pedestal/pedestal/issues/947

Thanks ... it came down to the namespace that provided the extend-protocol was not loaded in your application's case. See https://github.com/pedestal/pedestal/pull/948

Temporary work-around for beta-2: just require io.pedestal.http, even if you don't use anything there.

Does that occur during execution of incoming requests, or at startup?

A stack trace would be helpful.
