  • fwiw i am also seeing this issue. Until a newly created bucket's global DNS gets set up, presigned URLs generated with generate_presigned_url return a redirect and fail CORS. Specifying the region and s3v4 don't fix this but path addressing does, though path addressing will be retired for new buckets next september.Returning the region-specific virtual address would fix this problem, and there ...
