undefined method `to_json' for ["begin_scenario"]:Array when running cpp

I'm not sure, whether this is the problem with my configuration or not, but I guess,  the require statement will not hurt. At least then, I can run my wire steps. 

```
# language: en
Feature: Table
  In order to explain how to use tagbles
  I have to make this silly example

  Scenario: No tag   # features\table.feature:6
