I reproduced the problem I had yesterday in a kekkonen app. I edited the hello-world example. https://gist.github.com/borkdude/ab0fa75773ab08bdcca0f4d5b74f2c63 Start the app and browse to the swagger API. (s/optional-key :response/filter) s/Any will not show up in the example request body of echo-pizza.

This is the only request body that gives me problems, the rest of the entire app works…
