    "Accept-Encoding": "gzip, deflate, br", 
    "Cookie": "test2=;; test=;", 
    "Host": "httpbin.org", 
    "X-Amzn-Trace-Id": "Root=1-658d99f2-20a0e91a0f976a473a0ff84d"
  }
}

without fix:

{
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate, br", 
    "Cookie": "test2=hello2; test=\"\\073\"",
