I have solved the problem. this is a bug.
the "eventget" method in "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-filter-mutate-3.1.1/lib/logstash/filters/mutate.rb:368" should be "event.get"

Indeed. I wonder how that slipped through the test. Do you want to send a pull request to fix this?

Thank you for your invitation, but I saw the latest mutate source code, bug has been resolved
