slack hook not work on "slack_url" and "slack_channel"

[OptimusKe]

hi,
I use script like

scan --slack_url https://hooks.slack.com/services/mychannelxxx

and

scan --slack_channel mychannelxxx

then output
/usr/local/lib/ruby/gems/2.3.0/gems/fastlane_core-0.32.0/lib/fastlane_core/configuration/config_item.rb:56:in `valid?': 'slack_url' value must be a String! Found TrueClass instead. (RuntimeError)

/usr/local/lib/ruby/gems/2.3.0/gems/fastlane_core-0.32.0/lib/fastlane_core/configuration/config_item.rb:56:in `valid?': 'slack_channel' value must be a String! Found TrueClass instead. (RuntimeError)

is that bug??
