Error when using Aggregate Check with "honor_stash"

[makayez]

Running sensu-server 1.0.2, sensu-plugins-sensu 2.2.0, sensu-plugin (2.3.0, 1.4.5), when using the "honor_stash" switch, I receive the following error. I've tried this on a fresh install and fresh plugin install.

/opt/sensu/embedded/bin/ruby /opt/sensu/embedded/bin/check-aggregate.rb -a http://localhost:4567 -c agg-check-feeds -i --critical_count 1 -A 600

Check failed to run: undefined method 'delete_if' for nil:NilClass, ["/opt/sensu/embedded/lib/ruby/gems/2.4.0/gems/sensu-plugins-sensu-2.2.0/bin/check-aggregate.rb:164:in 'honor_stash'", "/opt/sensu/embedded/lib/ruby/gems/2.4.0/gems/sensu-plugins-sensu-2.2.0/bin/check-aggregate.rb:317:in 'run'", "/opt/sensu/embedded/lib/ruby/gems/2.4.0/gems/sensu-plugin-1.4.5/lib/sensu-plugin/cli.rb:58:in 'block in <class:CLI>'"]

aggregate is a hash, not an array. delete_if isn't a method on hash
