sbt pactVerify fails with incomprehensive error

[atsviatkou]

I have very simple pact file with health check endpoints

{
  "provider" : {
    "name" : "service-api"
  },
  "interactions" : [
    {
      "request" : {
        "method" : "GET",
        "path" : "/readiness"
      },
      "description" : "Fetching readiness response",
      "response" : {
        "status" : 200,
        "body" : {
          "result" : {
            "data" : [
              {
                "status" : "UP"
              }
            ],
            "total_count" : 1
          },
          "status" : 200
        }
      },
      "providerState" : "readiness"
    },
    {
      "request" : {
        "method" : "GET",
        "path" : "/liveness"
      },
      "description" : "Fetching liveness response",
      "response" : {
        "status" : 200,
        "body" : {
          "result" : {
            "data" : [
              {
                "status" : "UP"
              }
            ],
            "total_count" : 1
          },
          "status" : 200
        }
      },
      "providerState" : "liveness"
    }
  ],
  "consumer" : {
    "name" : "HealthCheckConsumer"
  },
  "metadata" : {
    "pactSpecification" : {
      "version" : "2.0.0"
    },
    "scala-pact" : {
      "version" : "2.3.17"
    }
  }
}

When I run command

sbt "pactVerify --host localhost --protocol http --port 9000 --source target/pacts"

I got error:

I get this error even if I start pactStubber

sbt "pactStubber --host localhost --port 9000 --source target/pacts"

and run verification against subbed services by command

sbt "pactVerify --host localhost --protocol http --port 9000 --source target/pacts"

The Pact files are the same for pactVerify and pactStubber

Environment

@atsviatkou did you set up a provider state called liveness? See http://io.itv.com/scala-pact/advanced/provider-states.html
