如何使用aws_cloudwatch_event_target覆盖resourceRequirements？

【以下的问题经过翻译处理】 我在Terraform中定义了一个AWS Batch作业，并在AWS中正常运行。我使用cronExpression（）创建了几个覆盖规则，以便在特定时间调用作业。我正在使用aws_cloudwatch_event_target和aws_cloudwatch_event_rule。大部分功能都正常工作。我使用正确的名称、arn等触发规则，即使是正确的命令。我的TF代码如下：

resource "aws_cloudwatch_event_rule" "batchjob" {
  name       = "foo"
  is_enabled = true
  # runs on the first of every month at 15:00 UTC 
  # https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/ScheduledEvents.html
  schedule_expression = "cron(0 15 1 * ? *)"
}

resource "aws_cloudwatch_event_target" "batchjob_target" {
  rule     = "foo"
  arn      = "<queue arn>"
  role_arn = "<role arn>"
  input = jsonencode({
    # https://docs.aws.amazon.com/batch/latest/APIReference/API_ContainerOverrides.html
    "ContainerOverrides" : {
      "Command" : [
        "/bin/java",
        "-jar",
        "/batch-jobs.jar",
        "foobar"
      ],
      # VCPU and MEMORY are linked: https://docs.aws.amazon.com/batch/latest/APIReference/API_ResourceRequirement.html
      # https://repost.aws/questions/QUP1kkGbDrT1uC4jTW6DXZ4A/set-cpu-and-memory-requirements-for-a-fargate-aws-batch-job-from-an-aws-cloudwatch-event
      "ResourceRequirements" : [
        {
          "Type"  = "VCPU"
          "Value" = "4"
        },
        {
          "Type"  = "MEMORY"
          "Value" = "8192"
        }
      ]
    }
    }
  )
}
batch_target {
  job_name       = "foo"
  job_definition = aws_batch_job_definition.job_definition.arn
}

我已确认“ContainerOverrides”和“Command”必须是pascal大小写才能正常工作。如果使用camel大小写，则看不到这些覆盖选项。
