Failure with a stacktrace from inside cucumber
It seems I have a too new cucumber or something. When I run the tests, it fails with a stack trace somewhere deep within cucumber itself.
I don't know ruby and I'm not familiar with cucumber much (definitely not with its internals), but if I was to make a guess, I'd say it expects a groups field in some answer which is not being provided. I have cucumber 3.0.1.

What is the „supported“ version?
TL;DR: I've not nothing yet, but here are some links to start looking with.
The intent is to support the latest version. Looking into this error but... man reading cucumber source is painful. Here's where I'm at so far:
group = step_argument.group from: https://github.com/cucumber/cucumber-ruby/blob/master/lib/cucumber/step_match.rb#L73
def initialize(step_definition, step_name, step_arguments) from: https://github.com/cucumber/cucumber-ruby/blob/master/lib/cucumber/step_match.rb#L10
result << StepMatch.new(step_definition, name_to_match, arguments) from: https://github.com/cucumber/cucumber-ruby/blob/88fe6414de548ad84c81c699911b246b8f979abd/lib/cucumber/glue/registry_and_more.rb#L67
The provided "arguments" are supposed to be StepDefinitions. I diverged from here to just try to find some type that has a group "method" or "value"
https://github.com/cucumber/cucumber-ruby/search?utf8=%E2%9C%93&q=group&type=
... And I came up empty. No method called "group" and no field called "group". I suspect that there may be something serialized (coming from upstream cucumber server?) that has this field. Lack of types in Ruby is really painful.
Yes, that's what I think too.
I had the idea of looking at some other language with a wire server how it does that (spy on it through wireshark), but so far I didn't manage to set anything working up yet.
Hmm. This one fails with the same exact error: https://github.com/cucumber/cucumber-cpp. How probable is it that nobody really uses the wire protocol and it was not tested and it is a bug in cucumber itself?
