We have already used firebase storage for storing the images and files in our application. Recently our files seem to bee not loading in the application and once cross-checking I found the following error.

{
  "error": {
    "code": 412,
    "message": "A required service account is missing necessary permissions. Please resolve by visiting the Storage page of the Firebase Console and re-linking your Firebase bucket or see this FAQ for more info: https://firebase.google.com/support/faq#storage-accounts"
  }
}

After further investigation, I found a solution in the below-related FAQ. https://firebase.google.com/support/faq/index#storage-accounts

As per the documentation, I have created a new service account with the I am admin role as Cloud Storage for Firebase Service Agent. It created a service account called service account name service-PROJECT_NUMBER@PROJECT_id.iam.gserviceaccount.com. Also, I have enabled the IAM admin policies for managing services. But still but storage URL is not loading.

Do I need to add any more changes to storage permissions? How can I use the existing storage bucket data with the new updates?

I just fixed this for my self.

1. Create a bucket in Cloud Storage
2. Get your projectname and bucket name
3. Go here: https://firebase.google.com/docs/reference/rest/storage/rest/v1beta/projects.buckets/addFirebase
4. Press Try IT
5. Fill in your projectname en bucket name. Press Execute é voila!

See my screenshot here

As mentioned in this github.

On the IAM page with the project owner role you will have an option to Grant Access. add this service account. service-project [email protected] as a principle, Cloud Storage for Firebase Service Agent as role.

If you are having trouble adding the service account ([email protected]) to the project, it's possible that Cloud Storage for Firebase has not created it yet.

Try using the AddFirebase API to relink a bucket to your project and try again: You can refer to this
