我正在尝试使用Ansible自动化Amazon Cloudfront发行版的配置。当前，我需要在Amazon Certificate Manager中查找证书的ARN（Amazon资源名称），并将ARN存储为变量，以便以后在Cloudfront发行配置中使用。

我对此的查询如下：

- name: Check for existence of a certificate for this project in Amazon Certificate Manager
  command: >
    aws acm list-certificates 
      --profile "{{ project_name }}"-deploy
      --region us-east-1 
  register: cert_list
  ignore_errors: True

- name: Record list-certificates output to Json  
  set_fact: 
    this_project_arn: # I want to set this from the output of list-certficates

- debug: msg="{{ cert_list.stdout | from_json }}"

该调试的输出当前如下：

TASK [configure-cloudfront : debug] ********************************************
ok: [localhost] => {
    "msg": {
        "CertificateSummaryList": [
            {

                "DomainName": …
