EACCES：AWS Lambda 上的权限被拒绝

Question

我已将我的文件路径添加为 /mnt/efs，但我仍然收到权限被拒绝的错误。

这是 CloudWatchlog：

您是否在 Lambda 附带的 IAM 角色中添加了 EFS 权限？检查此 link 以获得您可以在 IAM 角色中添加的 EFS 权限 https://docs.aws.amazon.com/efs/latest/ug/iam-access-control-nfs-efs.html

关于如何将IAM Role附加到Lambda检查 https://aws.amazon.com/blogs/security/how-to-create-an-aws-iam-policy-to-grant-aws-lambda-access-to-an-amazon-dynamodb-table/
