When trying to assoc a map into the [:session :identity] key (I’m using cookie-store) I get java.lang.RuntimeException: No reader function for tag object, it turns out the issue is caused by some values in my map that are java.time.ZonedDateTime instances.

I’m trying to pass the :readers key into (cookie-store …) but I can’t understand how it works, it seems like it stems from core.edn/read but the documentation seems extremely thin.
