我有一张Highcharts图表（https://jsfiddle.net/trevisan/uv6nuar0/）我正试图使用此命令导出到png
highcharts-export-server.cmd -fromFile .\my-chart.json
但似乎Highcharts Node.js导出服务器不接受 globalOptions 作为我的json文件中的参数，因为我收到此错误：
[error] phantom worker 1 unexpected data - SyntaxError: Expected token ']'
我假设我的json对象是正确的，因为如果我在网页中渲染图表，我会很好地工作（参见jsfidle）。
有人知道如何修复此问题或其他一些方法来包含要导出的defs选项吗？
这是my-chart.json文件内容：
