调研方向

使用两个 JSON 示例复现导出，然后检查 export.js 中第 157 行 setAsConfig 附近的配置评估路径，以及堆栈跟踪中显示的 triggerExport 调用。当包含转义双引号的 labelFormatter 代码能够成功导出且不再出现所报告的语法错误时，修复即完成。

由索引模型根据 Issue 内容生成。

描述

Export server version: v5.0.0
Highcharts version: 10.2.1

The only difference between these examples is in used quotes in labelFormatter. Only the first one works with export server.

{
  "infile": {
    "exporting": {
      "enabled": true
    },
    "xAxis": {
      "type": "datetime"
    },
    "legend": {
      "labelFormatter": "function () { if (typeof this.chart.series[0] !== 'undefined') { return this.chart.series[0].name; } return 'Somethign else';}"
    },
    "series": [
      {
        "name": "Temperature",
        "data": [
          {
            "x": 1743214500000,
            "y": 1
          }
        ]
      }
    ]
  }
}

{
  "infile": {
    "exporting": {
      "enabled": true
    },
    "xAxis": {
      "type": "datetime"
    },
    "legend": {
      "labelFormatter": "function () { if (typeof this.chart.series[0] !== \"undefined\") { return this.chart.series[0].name; } return 'Somethign else';}"
    },
    "series": [
      {
        "name": "Temperature",
        "data": [
          {
            "x": 1743214500000,
            "y": 1
          }
        ]
      }
    ]
  }
}

Export server logs and received response from export server for the second example:

{
  "statusCode": 400,
  "message": "[pool] In pool.postWork: For request with ID 935e61e6ae0f4356a2a2264867c6f423 - Error encountered during export: 8.110875ms."
}
