Integration with firebase giving 'main' module not found error

Please provide the following:

  1. SDK Version:45.0.0
  2. Platforms(Android/iOS/web/all): all
  3. Add the appropriate “Tag” based on what Expo library you have a question on.

I am trying firebase integration with expo but hitting the below error as soon firebase is imported.

Error message:
Error: While trying to resolve module idb from file C:\exampleApp\node_modules\@firebase\app\dist\esm\index.esm2017.js, the package C:\exampleApp\node_modules\idb\package.json was successfully found. However, this package itself specifies a main module field that could not be resolved (C:\exampleApp\node_modules\idb\build\index.cjs. Indeed, none of these files exist:

Hey @mduntoor, it seems like this is a new Firebase JS SDK release that breaks compatibility with react-native. A workaround for this is to downgrade the firebase dependency version to 9.6.2.

You can install it npm install firebase@9.6.2.
