I have a Firebase Cloud Function that invokes an Admin SDK service account to request the Remote Config template to compare changes to the previous version. I have this working in 2 other Firebase instances, but in this instance, I'm getting this error in the cloud function logs:
Function execution started
rejected token
"status": "PERMISSION_DENIED"
error encountered:
"error": {
"code": 403,
"message": "[AUTHORIZATION_ERROR]: User does not have the following permission: GET_TEMPLATE",
Function execution took 139 ms, finished with status: 'ok'
I have tried adding these permissions to the service account:
I have also tried deploying this cloud function on 3 different service accounts and they all receive the same error. Any suggestions would be most welcome.
This issue was resolved by adding the required permissions (cloudconfig.configs.get, cloudconfig.configs.update, and firebaseanalytics.resources.googleAnalyticsReadAndAnalyze) to the 'App Engine default service account'. This was confusing because we had thought that the default Firebase Admin SDK 'firebase-adminsdk-*****@projectId.iam.gserviceaccount.com' would be the default service account used to access the Remote Config GET_TEMPLATE. I know for certain we also tried manually specifying this service account when initializing the app in the Cloud Function. We even tried changing the 'Runtime service account' in the Cloud Function -> Edit -> 'Runtime, build, connections and security' settings to use the service account and that didn't work (which seems like that might be a bug). Only adding the correct permissions to the App Engine default service account seemed to work in this instance.
