Can someone point me in the right direction? I want config for duct.profile/local in local.edn to override our duct.profile/test configuration

so if I have local.edn:

{:foo.api/router {:request-diffs? false
                  :pretty-router-exceptions false}}

{:foo.api/router {:request-diffs? true} ... }}

I want :request-diffs? false to override the value in test.edn

I can see both respective keys and their values under their profiles when I call read-config but once we call prep-config with both profiles the value is always true

AFAIK you could look into the place where you prepare the config and search for profiles there. For example, the default dev.clj

...
(def profiles
  [:duct.profile/dev :duct.profile/local])
...
(integrant.repl/set-prep! #(duct/prep-config (read-config) profiles))
