让 ABCPDF Gecko Engine 将网页转换为 PDF。在本地工作正常，但是当推送到 azure webjobs 时，我不知道如何调试它。我不确定那行代码（3518）是什么，因为有不同的版本，并且它从没有代码的地方抛出错误。
C# 代码
var url = "http://www.woot.com";
Log("AddingImageUrl {0}", url);
var theID = _doc.AddImageUrl(url);
while (true)
{
if (!_doc.Chainable(theID))
{
break;
}
_doc.Page = _doc.AddPage();
SetupRectangle();
theID = _doc.AddImageToChain(theID);
}
