Create an application running this code:

StorageOptions.defaultInstance().service().readAllBytes(bucket, objectName)

It will work on a local environment using application default credentials, but it will throw the following error when deployed on App Engine standard (did not try on flexible):

com.google.cloud.storage.StorageException: 401

The workaround is to use Storage.reader() to get a ReadChannel.

This is strange and I believe it does not depend on us. I need to do some digging but I might have a fix.

@clementdenis Would you mind giving a try to #1010? that should fix the readAllBytes issue.
