Defined in:

Overview

Detects explicit ‘return` of non-Hash values inside runner modules. LEX runner methods must return a Hash so the framework can process the result and chain tasks correctly.

Examples:

# bad
module Runners
  module Foo
    def run
      return "error"
    end
  end
end

# good
module Runners
  module Foo
    def run
      return { success: false, message: "error" }
    end
  end
end
