我们的Lambda函数失败，原因：

我们还在用户界面上看到了一个通知：

要启用对象标记的复制，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，则必须对其进行更新。

Answer 1

我们遇到了这个AccessDenied错误

我们必须为IAM角色启用更多策略：

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

如您所见，有GetObjectTagging和PutObjectTagging的特定策略
