hi, i followed the yada tutorial and I seem to be getting the No implementation of method: :resolve-handler of protocol: #'bidi.bidi/Matched error.

this is my yada related code

(yada/listener
                         ["/"
                          [
                           ["hello" (yada/as-resource "Hello World!")]
                           ["test" (yada/resource {:produces "text/plain"
                                              :response "This is a test!"})]
                           [true (yada/as-resource nil)]]]
                         #_(routes/all  (get-in self [:database :connection]))
                         {:port 8080})

can anyone spot whats going on?

these are my versions

[yada "1.1.28"]
                 [aleph "0.4.1"]
                 [bidi "2.0.8"]
