Hi, it should work with 9 It's being tested with 9.5.0 in the repo https://github.com/pactflow/pact-cypress-adapter/blob/main/example/todo-example/package.json And 9.5.0 in our e2e demo https://github.com/pactflow/example-bi-directional-consumer-cypress/blob/28669a49080d16cfb62291c1a10d55b431d61474/package.json#L49 I've not tested it with 10 yet, I know there are some package changes like the removal of cypress.json and I need to do update some of my own cypress plugins to support ( possibly 🤔 ) What issue are you seeing above 8.2 and in 10?
