The gcloud storage buckets create command enables Uniform Bucket-Level Access (UBLA) by default. This is a change from gsutil mb, which created buckets with fine-grained access controls (ACLs enabled) by default.

When UBLA is enabled, ACLs are disabled. This will cause the next step, gcloud storage buckets update ... --predefined-default-object-acl=public-read, to fail. The application code, which uses blob.make_public(), would also fail.

To maintain the original behavior and ensure the sample works as described, you should explicitly disable UBLA during bucket creation.

Suggested change
$ gcloud storage buckets create gs://[your-bucket-name]
$ gcloud storage buckets create gs://[your-bucket-name] --uniform-bucket-level-access=false


3. Set the default ACL on your bucket to public read in order to serve files directly from Cloud Storage. You can do this with the [Google Cloud SDK](https://cloud.google.com/sdk) with the following command:

$ gsutil defacl set public-read gs://[your-bucket-name]
$ gcloud storage buckets update gs://[your-bucket-name] --predefined-default-object-acl=public-read

4. Update the environment variables in ``app.yaml``.
