如何使用CDK从ARN导入现有S3?

我正试图通过arn使用CDK导入一个现有的S3 bucket。

到目前为止,代码看起来像,

class MyStack(Stack):

    def __init__(self, scope: Construct, construct_id: str, **kwargs) -> None:
        super().__init__(scope, construct_id, **kwargs)

        s3_bucket_arn = CfnParameter(
            self,
            "S3_BUCKET_ARN",
            type="String"
        )

        s3_bucket = s3.Bucket.from_bucket_arn(
            self,
            "existing-bucket-from-arn",
            s3_bucket_arn.to_string()
        )

接下来,当我引导我的帐户时 cdk bootstrap --profile my-profile --parameters S3_BUCKET_ARN=arn:aws:s3:::my-bucket-arn 这引发了以下错误,

jsii.errors.JSIIError: ARNs must start with "arn:" and have at least 6 components: MyStack/S3_BUCKET_ARN
