node.js - 当Heroku中的product = firefox时Puppeteer不工作

Question

我做了什么 ：

我使用这些参数在 Heroku 中部署了我的应用程序

await puppeteer.launch({ product:'firefox',defaultViewport: null, args: ['--no-sandbox', '--disable-setuid-sandbox'] });

为 Heroku 添加了这个 buildpack：

https://github.com/jontewks/puppeteer-heroku-buildpack

我已经添加了

"preinstall": "PUPPETEER_PRODUCT=firefox npm install puppeteer"

在 package.json 中用于下载 firefox 依赖项。

当我尝试将其用于屏幕截图时，从日志中获取此错误

PS：在本地开发设置中工作正常。
