如何从Terraform向CloudFormation模板传递a列表？

variable "example_list" {
  type        = list(string)
  description = "Example list variable"
  default     = ["item1", "item2", "item3"]
}

resource "aws_cloudformation_stack" "example_stack" {
  name          = "example-stack"
  template_body = data.template_file.example_template.rendered
  parameters = {
    ListParameter = var.example_list
  }
}

data "template_file" "example_template" {
  template = file("cloudformation_template.json")
}

{
  "Resources": {
    "ExampleBucket": {
      "Type": "AWS::S3::Bucket",
      "Properties": {
        "BucketName": "example-bucket",
        "AccessControl": "Private",
        "BucketPolicy": {

            {

              "Action": [
                "s3:GetObject"
              ],
              "Resource": "arn:aws:s3:::example-bucket/*",
              "Condition": {
                "StringEquals": {
                  "aws:SourceVpce": [
                    "${ListParameter[0]}",
                    "${ListParameter[1]}",
                    "${ListParameter[2]}"
                  ]
                }
              }
            }
          ]
        }
      }
    }
  },
  "Outputs": {
    "ExampleList": {

    }
