{
  "_tag":"Right",
  "right":{
    "statusCode":200,
    "headers":{
      "x-powered-by":"Express",
      "content-type":"application/json; charset=utf-8",
      "content-length":"2",

    },
    "body":{
      
    }
  }
}

Expected Behavior

Error should be produced when response does not match OAS schema that includes an internal $ref. See #2363 for more details.

{
  "_tag":"Left",
  "left":[
    {
      "path":[
        "body"
      ],
      "code":"required",
      "message":"Request body must have required property 'output'",
      "severity":0
    }
  ]
}

Possible Workaround/Solution

See #2363

Steps to Reproduce

See test case

Using example schema

{
  "schema":{
    "type":"object",
    "properties":{
      "output":{
        "$ref":"#/__bundled__/OutputType"
      }
    },
    "required":[
      "output"
    ]
  }
}

With empty body

{ "body": {} }

validateOutput() did not produce any errors. Expected error about required property output
