amazon-web-services - 使用 cloudwatchevent_rule ansible 模块的 input_path 时参数的类型无效

Question

下面是我的 palybook.yml 文件的一部分，

- name: "cloudwatch event rule mapping with lambda"
  cloudwatchevent_rule:
    region: "{{ region }}"
    name: "{{ lambda_trigger.events_rule_name }}"
    schedule_expression: "{{ lambda_trigger.event_cron_expression }}"
    description: "{{ lambda_trigger.events_rule_name }}"
    targets:
      - id: "{{service_name}}"
        arn: "{{ lambda_arn }}"
        input_path: {"payload" : "$.detail.{{ lambda_trigger.payload | default({}) }}" }

错误：
