Original GitHub issue: https://github.com/quasar/Quasar/issues/1081

Describe the bug
I followed the instructions/examples here: https://quasar.dev/quasar-cli-webpack/developing-ssr/ssr-production-export#example-firebase-function

I uploaded the functions successfully, as we as the corresponding hosting setup. However when I access the deployed app and/or functions I am getting the following error:

ReferenceError: Cannot access 'WEBPACK_DEFAULT_EXPORT' before initialization at Module.default (chunk-837.js:39:42)

I also used "@quasar/app-webpack": "^3.5.3", as the docs mentioned

To Reproduce
Steps to reproduce the behavior:

Add mode ssr
Initialize firebase functions
Point the source path to dist/ssr
Modify the src-ssr/production-export.js file
Upload the the hosting and functions

Expected behavior
The app should work as intended

Screenshots

It seems this is not a problem with Quasar, I managed to make it work with a fresh simple project. Apparently it has to do with the imports within the app as discussed here. I still haven't figured out what's wrong with my work but I will update it here. Thanks.

OMG this is the wrong quasar. HAHAHAHA. My bad, I was supposed to open an issue to quasar framework. 😅
