Fluentd on Solaris test generates error: wrong number of arguments (1 for 0)

Recommended post-installation test doesn’t work:

echo ‘{“message”:“hello”}’ | fluent-cat debug.log

wrong number of arguments (1 for 0)

For the record: Solaris is not supported officially

Thank you… We were sure Fluentd by Ruby gems is supported on all OSes. Install By Gem - Fluentd
?

Could it be yajl-ruby issue?
