Not able to create the file on Google Cloud Storage

Question

I am following the below link.

https://github.com/GoogleCloudPlatform/getting-started-java/tree/master/bookshelf-standard/3-binary-data

I create a new Google Cloud Project and followed the above instructions and all fine on the remote server

I tried using an existing old appengine project (created 4-5 years ago). I get the following error at the given code:

"Caller does not have storage.objects.create access to bucket ..."

 storage.create(BlobInfo.newBuilder(bucketName, fileName)
 // Modify access list to allow all users with link to read file
   .setAcl(new ArrayList<>(Arrays.asList(Acl.of(User.ofAllUsers(), 
    Role.READER)))).build(),
 fileStream.openStream());

Following is the stacktrace

  Uncaught exception from servlet
  com.google.cloud.storage.StorageException: Caller does not have storage.objects.create access to bucket asw12.

I checked up the Google Service Accounts in my old project and it exists. How do I know, who is the 'Caller'?

If you use the google-cloud libraries from App Engine and don't otherwise specify, you will be acting as your project's app engine default service account. Its name is probably something like [email protected].

To get the service account name, open the Service Accounts page in the console, or check the settings on your App Engine page.
