The YAML parser in the newer ruby has changed and implements the spec a bit
differently
so this error is about malformed YAML - which could indeed have worked before.
You can test all your yamls like:
for i in $(find /etc/puppetlabs/code/hieradb -name \*.yaml)
do
/opt/puppetlabs/puppet/bin/ruby -r yaml -e "YAML.load(File.read('$i')) &&
puts('$i: OK') rescue puts('$i: NOT OK')"
done
change /etc/puppetlabs/code/hieradb to your hiera dir
