使用AWS-CDK，Python将块设备映射添加到EC2

Question

为ebs卷添加2个块设备映射时出现错误。我正在使用aws-cdk，python。

这是代码

    from aws_cdk import core
    from aws_cdk import aws_ec2 as _ec2

    #Webserver 01
    webserver = _ec2.Instance(
        self,
        "webserver01Id",
        instance_type = _ec2.InstanceType(instance_type_identifier="t2.micro"),
        instance_name = "webserver001",
        machine_image = _amzn_linux_ami,            
        vpc=vpc,
        vpc_subnets = _ec2.SubnetSelection(subnet_type=_ec2.SubnetType.PUBLIC),
        user_data = _ec2.UserData.custom(_user_data),
        block_devices= {"block_device_mappings": [
            {"device_name ": '/dev/sda1', "volume": _ec2.BlockDeviceVolume.ebs(50)}, 
            {"device_name": '/dev/sdm', "volume": _ec2.BlockDeviceVolume.ebs(100)}
            ]
        } 
    )

这是我遇到的错误。

jsii.errors.JSIIError：预期的数组类型，得到了{“ $ jsii.map”：{“ block_device_mappings”：[{“ $ jsii.map”：{“ device_name”：“ / dev / sda1”，“ volume “：{” $ jsii.byref“：” @ aws-cdk/aws-ec2.BlockDeviceVolume@10012“}}}，{” $ jsii.map“：{” device_name“：” / dev / sdm“，” volume “：{” $ jsii.byref“：” @ aws-cdk/aws-ec2.BlockDeviceVolume@10013“}}}]}} 子流程退出，错误1

用于aws_ec2.Instance类的CDK API 1.63.0的最新版本规定block_devices应该是aws_ec2.BlockDevice实例link here的列表，而不是{{1 }}。
