How to post a http request without cookie in headers?

Here is my pact file

    {
  "consumer": {
    "name": "consumer"
  },
  "provider": {
    "name": "provider"
  },
  "interactions": [
    {
      "description": "for pact",
      "providerState": "test service.",
      "request": {
        "method": "post",
        "path": "/uri",
        "headers": {
          "Content-Type": "application/json"
        },
        "body": {
          "key": "value"
        }
      },
      "response": {
        "status": 200,
        "body": {
          "key": "value"
          }
        }
      }
    }
  ],
  "metadata": {
    "pactSpecification": {
      "version": "2.0.0"
    }
  }
}

And get the header of post request by wireshark :

POST /uri HTTP/1.1
Cookie: 
Host: 127.0.0.1:8080
Content-Length: 57
Content-Type: application/json 

Due to the exist of Cookie in header, my provider can not response correctly. How can I remove it from header?

Looks like it sets a blank cookie for every request. Unfortunately, there’s nothing the pact library can do about that.

Closing as a won’t fix.
