Hi there, @mrj04! It's quite difficult for me to figure out how to help you based on the stack trace alone. Could you please give me a bit more context and explain what you're trying to do?

@mrj04 I had the same error while I was configurating, it turns out I had installed CucumberJS 2+ when SerenityJS only supports Cucumber 1+. You can check your version of CucumberJS.
