我们还在用户界面上看到了一条通知:

要启用对象标签的复制，如果用于跨区域复制的 IAM 策略是在引入对象标记之前创建的，则必须更新这些策略。

我们遇到了这个 AccessDenied 错误

我们必须为我们的 IAM 角色启用进一步的策略:

"Action": [
                "s3:PutObject",
                "s3:GetObjectAcl",
                "s3:GetObject",
                "s3:GetObjectTagging",
                "s3:PutObjectTagging",
                "s3:PutObjectAcl"
],
