I am trying to use Cucumber.js but for some reason the snippet generation is broken. I am not sure if my setup is wrong or if there's a bug in cucumber-js itself.
I setup a simple test project https://github.com/cwansart/cucumber-js-test and ran npx cucumber-js which throws the following errors:
TypeError: this.parameterTypes is not a function
at CucumberExpressionGenerator.createParameterTypeMatchers (/home/runner/work/cucumber-js-test/cucumber-js-test/node_modules/@cucumber/cucumber-expressions/dist/src/CucumberExpressionGenerator.js:110:41)
at CucumberExpressionGenerator.generateExpressions (/home/runner/work/cucumber-js-test/cucumber-js-test/node_modules/@cucumber/cucumber-expressions/dist/src/CucumberExpressionGenerator.js:27:42)
Error: Process completed with exit code 1.
See: https://github.com/cwansart/cucumber-js-test/runs/1854253039
I tried to find the issue in the cucumber code but have not been successful so far.
The tests work then I add the then block in the features/support/steps.js again.
How to fix this?
Nothing wrong at all with what you're doing (thanks for the test repo btw, that helped), it's an issue with a new version of a dependency.
Here's the GitHub issue: https://github.com/cucumber/cucumber-js/issues/1571
There'll be a patch version of cucumber-js coming soon to address this but in the meantime if you override the version of @cucumber/cucumber-expressions in your project to 11.0.0 (so it doesn't pick up 11.0.1) that should work around it.
Update: A patch has been released to revert the issue:
we've just released cucumber-expressions version 11.0.2 which fixes a regression from 11.0.1. If you
npm update[in your project] the problem should go away.
