如何解决NodeJS Server pdf文档生成问题
我正在研究一个API，该API基于EJS模板生成pdf文档，然后将其通过电子邮件发送给某些用户。在本地运行时，一切正常，但是当我的API推送到heroku时，会生成pdf，但出现一些奇怪的格式错误。就像页面实际上是在垂直方向上向下切开一样。
有人知道这可能的原因吗？
我正在使用ejs和html-pdf
这是代码和模板

ejs.renderFile(path.join(__dirname,'../views/',"offer.ejs"),{offerData},(err,data) => {
if(err)
reject(err)
else
{
const options = {
"height": "11.25in","width": "8.5in","header": {
"height": "10mm"
},"footer": {
"height": "10mm",}
};
//creates the actual pdf doc for sending
pdf.create(data,options).toFile(`./offer_${inqID}.pdf`,function(err,res) {
if (err)
reject(err)
else
resolve(res.filename)
});
}
});
