[Encountered Issue: Phenomenon and Impact]

  1. When using dumpling version v6.5.9 for backup, an error occurs: create dumper failed: s3 bucket and region are not matched, bucket=mysql_backup, input region=mysql_backup, real region=us-east-1
  2. When using the same version of dumpling v4.0.10 for backup, no error occurs

The error seems to be a mismatch between the bucket and the region.
Try verifying with a command like this: aws s3 ls s3://mysql_backup --region us-east-1
