Hi folks, I am trying to follow the bi-directional contracts tutorial, but I am having trouble on Step 10. When I have to comment out the price field, I am getting a 409 - Conflict error at publishing the new OAS contract. Basically what I did was to add a # before each price: string + removing the whole entry on components.schemas.Product.properties. Here is my OAS contract. Am I doing something wrong? You can find my current contract here: https://thatsabug.pactflow.io/contracts/bi-directional/provider/pactflow-example-provid[…]ountebank/version/d1db1c-master%2Bd1db1c/provider-contract

I think you’ll only get a

409

if you try publishing with the exact same version - are you bumping the version?

Indeed. I've changed the OAS version and I could upload. Thanks @Matt (pactflow.io / pact-js / pact-go) Probably it is obvious for people who understand OAS written-by-hand, but for a newbie like me, it wasn't 😄

hahah glad to hear it’s solved!
