JSON 正则表达式模式

Question

我正在使用 JMeter 来测试我们的 API，但是（我认为）当字符串太大时，JMeter 会引发错误。我得到一个普通文本的结果，但是当我在结果树中选择 JSON 格式时，我得到了这个错误，我无法再查看响应。当我尝试使用不太大的字符串的不同响应时，我可以毫无问题地查看结果。

这是我发送给服务器的请求

{
    "event_id":"592929"
}

这就是响应

{
  "status": 1,
  "message": "Success",
  "result": {
    "data": [
      {
        "Event": {
          "event_id": 592929,
          "name": "",
          "description": "",
          "time": "2016-01-02 22:00:00",
          "venue_address": "",
        }
      },
      {
        "Venue": {
          "id": 1022,
          "name": "",
          "street": "",
          "postcode": "",

        }
      },
      {
        "Ticket": {
          "ticket_id": 567828,
          "ticket_price": "10.00",
          "sold_out": 0,
          "ticket_url": "",
          "available": 1
        }
      }
    ]
  }
}

现在，取决于我发送的值（以及我得到的结果），它要么正常工作，我可以查看 JSON 响应，要么不正常，当在结果树上选择 JSON 时，它给了我这个大错误.

这仅在使用 JMeter 时。我尝试使用 Postman，查看结果没有问题。
