I think the last line of the code example on page 110 is missing a closing bracket and end parens.
Should be:
{:errors {:server-error [“Failed to save message!”]}}))))))}}]])
In the source code, it appears like this:
{:errors {:server-error [“Failed to save message!”]}}))))))}}]
;
])
Thanks for the great book! It’s been instrumental in understanding of practical Clojure.
