Description

When using Firebase service account JSON file and use flutterfire reconfigure instead of flutterfire configure on CI, it fails.

This was requested before at #232

Steps to reproduce

Add Firebase service account JSON to your secrets and try running the following on CI:

• name: Add Firebase service account credentials files
  env:
  FIREBASE_SERVICE_ACCOUNT: ${{ secrets.FIREBASE_SERVICE_ACCOUNT }}
  run: |
  echo $FIREBASE_SERVICE_ACCOUNT > /tmp/google-application-credentials.json
• name: Configure Firebase
  env:
  GOOGLE_APPLICATION_CREDENTIALS: /tmp/google-application-credentials.json
  run: flutterfire configure ...... // Complete your project configurations

It should run successfully, but If you use flutterfire reconfigure, it'll fail with the following error:

Failed to write android google-services.json file write for build configuration: "src/dev". Please report this issue at:https://github.com/invertase/flutterfire_cli. Exception: type 'Null' is not a subtype of type 'Map<String, dynamic>' in type cast

Expected behavior

I expect flutterfire reconfigure to work on CI.

@AhmedLSayed9 - Is there a stack trace to go with it?

What does your firebase.json look like for android, specifically for this build configuration src/dev. Redact any sensitive strings, only concerned with structure.

Have you reproducing locally?

It's going to be one of these if it is android I think:

https://github.com/invertase/flutterfire_cli/blob/main/packages/flutterfire_cli/lib/src/commands/reconfigure.dart#L393
https://github.com/invertase/flutterfire_cli/blob/main/packages/flutterfire_cli/lib/src/commands/reconfigure.dart#L415

Is the firebase.json in the root of the project?

The firebase.json configuration seems correct to me. A local repro would be helpful.

[AhmedLSayed9]

flutterfire reconfigure works fine locally

[AhmedLSayed9]

The difference is locally I'm logged in using firebase login but at the CI I'm using firebase service account credentials.

Yes

[russellwheatley]

The difference is locally I'm logged in using firebase login but at the CI I'm using firebase service account credentials.

I don't think this should make a difference. Not sure what the problem is, It's saying something that is expected to be a map (from those lines I pasted earlier), is null.

You ought to put some debug logs on firebase.json path, content, etc to find out why map is empty. It's clearly a difference between your CI and local environment.

@russellwheatley

I was able to reproduce it using a minimal sample: https://github.com/AhmedLSayed9/firebase_test

Check the workflow: https://github.com/AhmedLSayed9/firebase_test/actions/runs/12951734235/job/36127428141

To reproduce:

1. Clone the repo, add a firebase project to it and update firebase.json file.
2. Add an environment secret to your repo that includes the service account json with the name FIREBASE_SERVICE_ACCOUNT.
3. Update --project=test-c7826 at .github/workflows/build.yml to your project id.
4. Try running the CI workflow
