net::ERR_ADDRESS_UNREACHABLE at {URL}

Question

>我在 nodejs 中使用 puppeteer v1.19.0，在 docker 中构建和运行后无法访问错误， 是 js 文件

await puppeteer.launch({
executablePath: '/usr/bin/chromium-browser',
args: ['--no-sandbox', '--disable-setuid-sandbox', '--headless'],
}).then(async (browser) => {
const url = `${thisUrl}analisa-jabatan/pdf/${_id}`
const page = await browser.newPage()
await page.goto(url, { waitUntil: 'networkidle0' })
// await page.evaluate(() => { window.scrollBy(0, window.innerHeight) })
await page.setViewport({
width: 1123,
height: 794,
})
setTimeout(async () => {
const buffer = await page.pdf({
path: `uploads/analisa-jabatan.pdf`,
displayHeaderFooter: true,
headerTemplate: '',
footerTemplate: '',
printBackground: true,
format: 'A4',
landscape: true,
margin: {
top: 20,
bottom: 20,
left: 20,
right: 20,
},
})
let base64data = buffer.toString('base64')
await res.status(200).send(base64data)
// await res.download(process.cwd() + '/uploads/analisa-jabatan.pdf')
await browser.close()
}, 2000)
})
}

并且是码头工人文件

来自木偶师文档：

当远程服务器返回任何有效的 HTTP 状态代码(包括 404"未找到"和 500"内部服务器错误"(时，page.goto 不会引发错误

因此，如果 URL 有效，服务器似乎不会发送响应。
