Hi Mark, Best asking PactFlow specific questions in our dedicated channel. You need to add a content type for the document you are uploadeding,

application/json

in your respect as its a JSON document, although application/yaml will work, the parser will accept both https://docs.pactflow.io/docs/bi-directional-contract-testing/contracts/oas#docker-1

Will do in the future. And thanks everything is worked as expected now!

It's okay, we've all done it! And saweet that you are sorted, happy tinkering
