Tried this hook with letsencrypt.sh. Looks like there is an issue when it runs with the latest version of awesome_print(1.7.0).
Throws error: awesome_print-1.7.0/lib/awesome_print/formatter.rb:122:in
method': undefined method
to_hash' for class `Seahorse::Client::Response'It works fine with awesome_print-1.6.1. Thanks.
