🐛 [AWS S3] Incorrect handling 301 error for specifying AWS region explicit: BucketRegionError: incorrect region

[bas-kirill]

EC2 configuration:

• AMI name: ubuntu/images/hvm-ssd/ubuntu-jammy-22.04-arm64-server-20240207.1
• Instance type: t4g.micro

During mounting using command:

./geesefs --no-checksum --memory-limit 4000 --max-flushers 32 --max-parallel-parts 32 --part-sizes 25 --file-mode=0666 --dir-mode=0777 --region eu-west-1 --endpoint https://s3.amazonaws.com kirill.bas /tmp/geesefs2

Got an error:

main.FATAL Mounting file system: Unable to access 'kirill.bas': BucketRegionError: incorrect region, the bucket is not in 'eu-west-1' region at endpoint 'https://s3.amazonaws.com'
        status code: 301, request id: , host id: 

My bucket at eu-west-1:

But if I use command without --region eu-west-1 everything works ok: s3.INFO Switching from region 'us-east-1' to 'eu-west-1' main.INFO File system has been successfully mounted.

./geesefs --no-checksum --memory-limit 4000 --max-flushers 32 --max-parallel-parts 32 --part-sizes 25 --file-mode=0666 --dir-mode=0777 --endpoint https://s3.amazonaws.com kirill.bas /tmp/geesefs

Steps to reproduce error:

1. Install geesefs:

sudo su

apt update -y
apt install golang-go -y  # installing "go" cli command
git clone https://github.com/yandex-cloud/geesefs /home/ubuntu/geesefs
cd /home/ubuntu/geesefs
go build

2. Create mount folder: mkdir /tmp/geesefs
3. Mount: ./geesefs --no-checksum --memory-limit 4000 --max-flushers 32 --max-parallel-parts 32 --part-sizes 25 --file-mode=0666 --dir-mode=0777 --endpoint https://s3.amazonaws.com <bucket-name> /tmp/geesefs

Expected Result: S3 mounted at /tmp/geesefs

Actual Result: got an error main.FATAL Mounting file system: Unable to access 'kirill.bas': BucketRegionError: incorrect region, the bucket is not in 'eu-west-1' region at endpoint 'https://s3.amazonaws.com' status code: 301, request id: , host id:
