title: Alamofire Version 5.2.0 and 5.2.1 both Crash at URL Session delegate
body: <p>I am using latest alamofire version 5.2.1 to make WEB API calls it working perfect with all apis
  But when i call api for country list it crash at URL Session Delegate class</p>
  
  <pre><code> open func urlSession(_ session: URLSession, dataTask: URLSessionDataTask, didReceive data: Data) {
          eventMonitor?.urlSession(session, dataTask: dataTask, didReceive: data)
  
          if let request = request(for: dataTask, as: DataRequest.self) {
              request.didReceive(data: data)
          } else if let request = request(for: dataTask, as: DataStreamRequest.self) { //Crash at this line
              request.didReceive(data: data)
          } else {
              assertionFailure("dataTask did not find DataRequest or DataStreamRequest in didReceive")
              return
          }
      }
  </code></pre>
  
  <p>The same request works perfect with normal url session and postman only alamofire cannot handle the response i am attaching screen shot for more detail.</p>
  
  <p><strong>Response contains 2000 line json but i don't think that's the problem</strong> </p>
