CDN region setting introduced

Added the ability to specify a custom AWS region for a store's media bucket, and fixed backoffice file operations to consistently use the same bucket, region, and credentials.

This includes:

• Configurable custom AWS region for a store's media bucket

• Fixes upload failures for buckets outside the default region

• Fixed mismatch between upload/listing bucket and the copy/move bucket

• All file operations now consistently target the same per-store bucket, region, and credentials

How it benefits the Merchant

This resolves media upload failures for merchants using non-default AWS regions, ensuring product images and other assets upload reliably. This resolves file upload failures for merchants using a custom CDN bucket, ensuring backoffice file management works reliably end-to-end.

Potential FAQs

A: No — this setting is specifically needed for stores using buckets outside the default AWS region.

Q: Will this fix apply automatically to my existing bucket configuration?

A: You need to specify the custom region setting for your bucket for this fix to take effect.
