CodePipeline：操作“2ndSource”的操作配置包含未知配置“PollForSourceChanges”

Question

有基于两个 Github 源的 AWS CodePipeline。要求是仅限制主要源的管道自动触发。从 terraform aws 样本中找到这个片段以禁用自动触发。

我尝试了同样的方法但出现错误（也使用最新的 hashicorp/aws“4.57.1”版本进行了测试）-

错误：更新 CodePipeline (xxxx)：InvalidActionDeclarationException：操作“2ndSource”的操作配置包含未知配置“PollForSourceChanges”

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 4.57.1"

}

resource "aws_codepipeline" "service" {
