# Invalid Firebase configuration

### Build failure: Invalid Firebase configuration

If your app build is failing, your build is not working, or your download is not completing and you see the message:

*“Your last build failed. Details entered are either incorrect or invalid.”*

This usually indicates an issue with your Firebase configuration settings. Incorrect, incomplete, or mismatched Firebase details can cause both Android and iOS build failures.

#### Why this build failure happens

1. Incorrect Firebase project settings
   * The wrong Firebase project is connected
   * Required services are not enabled
2. Invalid or mismatched keys and IDs
   * Package name or Bundle ID does not match Firebase
   * Any key, ID or credentials are incorrect
3. Social login misconfiguration (if enabled)
   * Google Sign-In is not configured correctly
   * OAuth credentials are missing or incorrect

#### How to fix this build failure

1. Verify your Firebase project
   * Log in to the [Firebase Console](https://console.firebase.google.com/)
   * Open the Project settings connected to your app
   * Ensure the correct Android package name or iOS Bundle ID is added

{% hint style="warning" %}
The package name (Android) or Bundle ID (iOS) in Firebase must exactly match the one configured in your app Download dashboard.
{% endhint %}

2. Check Firebase configuration settings
   * Confirm that the app is properly registered in Firebase
   * Verify that all required services are enabled
   * Review any credentials entered in your dashboard

Even a small mismatch or missing value can cause the build to fail.

3. Review social login setup (if enabled)
   * Ensure Google Sign-In is enabled in Firebase
   * Confirm that SHA keys (for Android) are correctly added
   * Verify OAuth credentials
4. Rebuild your app
   * Go to the Download section
   * Click Rebuild under the relevant app card

Once all Firebase settings are corrected, your build failure should be resolved and the download should complete successfully.
