我有一个URL，其中包含一些JSON数据。我想解析这些数据并使用Python转换为字典。网页上的第一行数据不是JSON格式的，所以我想在解析前跳过第一行。网页上的数据如下所示：

expected 1 issue, got 1
{
  "Issues": [
    {
      "issue": {
        "assignedTo": {
          "iD": "2",
        },
        "count": "1117",
        "logger": "errors",
        "metadata": {
          "function": "_execute",
          "type": "IntegrityError",
          "value": "duplicate key value violates unique constraint \nDETAIL:  Key (id, date, reference)=(17, 2020-08-03, ZER) already exists.\n"
        },
        "stats": {},
        "status": "unresolved",
        "type": "error"
      },
      "Events": [
        {
          "message": "Unable to record details",
          "tags": {
            "environment": "worker",
            "handled": "yes",
            "level": "error",
            "logger": "errors",
            "mechanism": "logging",
          },
          "Messages": null,
          "Stacktraces": null,
          "Exceptions": null,
          "Requests": null,
          "Templates": null,
          "Users": null,
          "Breadcrumbs": null,
          "Context": null
        },
      ],
      "fetch_time": "2020-07-20"
    }
  ]
}

我试着运行这个脚本：

with urllib.request.urlopen("[my_url_here]") as url:
    if(url.getcode()==200):
        for _ in range(1):
            next(url)
        data = url.read()
        json=json.loads(data)
    else:
        print("Error receiving data", url.getcode())

但我遇到了错误：

Traceback (most recent call last):
  File "<stdin>", line 6, in <module>
  File 
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

当我运行它而不使用

for _ in range(2):
            next(url)

...但最后一行为“期望值：行2列1（char 1）'。
有什么建议吗？谢谢
