can not find module fs when installing @nativescript/firebase-crashlytics

Hi all

When I add "@nativescript/firebase-crashlytics" to my Nativescript app, the compilation fails with the following error:

***** Fatal JavaScript exception - application has been terminated. *****
NativeScript encountered a fatal error: Uncaught Error: Cannot find module 'fs'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
- add a fallback 'resolve.fallback: { "path": require.resolve("path-browserify") }'
- install 'path-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
resolve.fallback: { "path": false }

Is there a way to fix this?

thank you

Reproduce the NativeScript app build with @nativescript/firebase-crashlytics and inspect the reported dependency path through node_modules/source-map/lib/read-wasm.js, source-map/lib/util.js, and the webpack output. The work is done when the app compiles and runs without the Cannot find module 'fs' error.
