For anyone else who might make the same mistake I did, I changed this:
(GET "/admin" request (friend/authorize #{::admin} (admin
request)))
to this:
(GET "/admin" request (friend/authorize #{::admin} {} (admin
request)))
adding an empty map before the string that is my actual HTML page.
That resolved the error in the stack trace.
However, my login still fails. I copy and paste both the username and
password, very carefully, into the login form, and hit submit, only to
get redirected to:
http://localhost:30000/login?&login_failed=Y&username=
I have not idea why this fails. I thought I had followed the
documentation carefully, but I suppose there is always something that
I miss.
