I created an unlocked Salesforce package that contains an External Service and an Inactive Autolaunched Flow that calls methods in the External Service. The package does not contain any Apex classes other than those auto-generated when creating the External Service. However, I am unable to promote my package to a production release version because it is saying that I haven't met the code coverage requirements.
What needs to have code coverage? The External Service? The Flow?
I read that Flow testing requirements apply only when DEPLOYING them as active, but does that apply to packaging as well?
