之前都是有数据的，现在怎么没数据产生了

代码如下

```js

    wx.reportEvent('wxdata_perf_monitor', {

        "wxdata_perf_monitor_id": url,

        "wxdata_perf_monitor_level": 0,

        "wxdata_perf_error_code": code,

        "wxdata_perf_error_msg": msg,

        "wxdata_perf_cost_time": duration,

        "wxdata_perf_extra_info1": "",

        "wxdata_perf_extra_info2": "",

        "wxdata_perf_extra_info3": "",

    });

```
