Clojurians Log v2

somewhat surprisingly, this works:

(-> (m/explain [:+ [int? {:error/message "Custom"}]] []) (me/humanize))
[["Custom"]]

this is because the actual end-of-input error is associated with the child schema:

(m/explain [:+ int?] [])
{:schema [:+ int?], :value [], :errors ({:path [0], :in [0], :schema int?, :value nil, :type :malli.core/end-of-input})}

this allows you to distinguish where the input ended, and react accordingly:

user=> (def int-and-string [:cat [int? {:error/message "didn't get an int"}] [string? {:error/message "didn't get a string"}]])
#'user/int-and-string
user=> (-> (m/explain int-and-string []) (me/humanize))
[["didn't get an int"]]
user=> (-> (m/explain int-and-string [1]) (me/humanize))
[nil ["didn't get a string"]]

wow it is difficult to write the right code in the repl 🤦

first, I thought -resolve-root-error was meant for this exact case

but it didn't work for me in the repl, but that was because I was running the wrong code

me/-resolve-root-error does do the trick here:

(-> (m/explain [:+ {:error/message "Custom message"} int?] []) (me/humanize {:resolve me/-resolve-root-error}))
["Custom message"]

Thanks, that's what I was trying to accomplish 😊 Now the next problem is that I don't actually call me/humanize myself. The schema is used in a reitit route:

...
:parameters {:body [:map
                      [:dvp-id int?]
                      [:tilganggrupper [:+ {:error/message "Custom message"} int?]]]}

(malli-coercion/create
    {:error-keys #{:humanized}
     :encode-error #(set/rename-keys % {:humanized :errors})})

I think you need to use :error-keys #{:errors} and do the humanize yourself in your exception handler
