Blank page after updated app build

[jbuese]

We have been experiencing this problem for some time now and cannot seem to find a solution. After we deploy changes, users get a completely blank page. The only fix is to reload the page. The problem seems to occur on desktop browsers (chrome, firefox, edge) and also on mobile PWA.

TypeError: s._s is undefined            index.js:26:21976

For the image, I tried to comment out the dark-mode.js code (specifically the Dark.set(darkMode); which seemed to be the culprit for the .set not being available), but got the above error instead.
I have not seen the local development bug yet - I assume it has something to do with the build.

This is what our docker file is executing (through npm in package.json of course):
quasar build -m pwa

This is our config:

export default defineConfig((ctx) => {
  return {
    boot: [
      "i18n",
      "axios",
      "auth",
      "emitter",

      "quasar-lang-pack",
      "dark-mode",
      "set-defaults",
    ],

                },
              },
