I just started playing with pactflow cli but while trying to publish a contract to our broker, I get the following error:

./pact/bin/pactflow publish-provider-contract ./<contract>.json --broker-base-url https://<url>.<http://pactflow.io/|pactflow.io/> --provider "<provider>" --provider-app-version 0.0.1
Error making request to https://<url>.<http://pactflow.io/provider-contracts/provider/<provider>/publish|pactflow.io/provider-contracts/provider/<provider>/publish> status=400 {"errors":{"_body.contract.contentType":["is missing"]}}

provider
    .given("a test")
    .uponReceiving("a request")
    .withRequest({
      method: "GET",
      path: "/endpoint",
      headers: { 'Content-Type': 'application/json' }
    })
    .willRespondWith({
      body: like(jsonResponse),
      status: 200,
      headers: { 'Content-Type': 'application/json', 'Accept': 'application/json' }
    });

any idea what am I missing?

the test you have written is for a consumer contract

facepalm RTFM thanks!
