Hi @johnksv - Thanks for the contribution, some relevant INT output:

Error: googleapi: Error 400: Project - may not create storageClass MULTI_REGIONAL buckets with locationConstraint EU and data_location europe-north1, data_location europe-west1.., invalid

[johnksv]

Hi @apeabody
Thanks.
I updated the example in simple bucket instead of multiple_buckets, due to the lifecycle in multiple_buckets causing collision with dual region/custom_placement_config setup.
