在Canonical Snap环境中运行基于Puppeteer的Node.js应用时的异常问题排查求助

我开发了一个依赖Puppeteer调用Chromium的Node.js应用，为了打包成Snap格式，我编写了对应的snapcraft.yaml配置，但在构建和运行过程中遇到了两类诡异的问题，折腾了好一阵没找到根源，希望有经验的朋友能帮忙分析一下。

我的snapcraft.yaml配置 #

Puppeteer启动配置 #

const browser = await puppeteer.launch({
        executablePath: process.env.SNAP + '/bin/chromium.launcher',
        headless: true,
        dumpio: true,
        userDataDir: process.env.SNAP_DATA,

            '--no-sandbox',
            '--disable-setuid-sandbox',

            '--no-zygote',
            '--disable-notifications',
            '--disable-features=WebRtcHideLocalIpsWithMdns',
        ],
    })
    const page = await browser.newPage()
    await page.setViewport({ width: 1920, height: 1080 })

问题1：浏览器能启动但无法访问目标网站，日志输出如下 #

Server is running on http://localhost:3000
[400316:400341:0327/031850.847874:ERROR:bus.cc(408)] Failed to connect to the bus: Could not parse server address: Unknown address type (examples of valid types are "tcp" and on UNIX "unix")
(process:400316): GLib-GIO-CRITICAL **: 03:18:52.838: g_settings_schema_source_lookup: assertion 'source != NULL' failed
[400316:400316:0327/031853.049242:ERROR:platform_font_skia.cc(255)] Could not find any font: , sans. Falling back to the default

问题2：有时迭代应用代码或修改snapcraft.yaml后，浏览器直接启动失败，报错 #

error while loading shared libraries: libOSSlib.so: cannot open shared object file: No such file or directory

这两个问题时有时无，实在摸不着头脑，麻烦各位帮忙看看可能的原因，感激不尽！
