S3 Object storage uploads fail with unclear message if region not specified
Summary
Uploading artifacts to an S3 compatible storage (minio) with consolidated object storage fails.
Steps to reproduce
- Configure consolidated object storage (to minio or s3, I think both would exhibit the same behaviour): https://docs.gitlab.com/ee/administration/object_storage.html#consolidated-object-storage-configuration
- Uploading an artifact with gitlab CI
- Observe the following error in the job output:
WARNING: Uploading artifacts as "archive" to coordinator... failed id=44102 responseStatus=500 Internal Server Error status=500 token=gZZiPr18
WARNING: Retrying... context=artifacts-uploader error=invalid argument
WARNING: Uploading artifacts as "archive" to coordinator... failed id=44102 responseStatus=500 Internal Server Error status=500 token=gZZiPr18
WARNING: Retrying... context=artifacts-uploader error=invalid argument
WARNING: Uploading artifacts as "archive" to coordinator... failed id=44102 responseStatus=500 Internal Server Error status=500 token=gZZiPr18
What is the current bug behavior?
Uploads fails
What is the expected correct behavior?
Uploads should work
Relevant logs and/or screenshots
After receiving the errors I did a tcpdump, this is the request:

Personally I think minio is right, AWS S3 does not support chunked uploads like that to the best of my knowledge.
Logs show the failure as well:

I found a workaround by issuing:
Feature.disable(:use_workhorse_s3_client)
which seems to trigger the (older?) working multipart upload again: https://gitlab.com/gitlab-org/gitlab/-/blob/master/workhorse/internal/filestore/file_handler.go#L133-149
