How I Encounter This Issue
When i pull a existing project on Github and about to setup it’s Firebase and generate the
firebase_option.dart file. After running
flutterfire configure i saw the error message below:Error Message
Failed to write android google-services.json file write for default service file. Please report this issue at:https://github.com/invertase/flutterfire_cli. Exception: Exception: Failed to obtain an access token for making Firebase Management REST API requests. Status code: 400. Response body: { "error": "invalid_grant", "error_description": "Bad Request" } Exception: Failed to obtain an access token for making Firebase Management REST API requests. Status code: 400. Response body: { "error": "invalid_grant", "error_description": "Bad Request" }
So, it seems that my access token to Firebase management API has some problem.
Solution
Here, we just try to re-login on Firebase CLI to refresh the access token.
firebase login --reauth
