Hello, i have an Array which can be empty or have 1 or 2 Entries. For multiple Entries i would have used Eachlike? But what about the case if its empty. Do i have to add an extra interaction for that or is there another way ?

You need two interactions: see https://docs.pact.io/faq#why-is-there-no-support-for-specifying-optional-attributes

Thank you for your help
