如何正确使用Ansible中的when条件

Question

---
- name: test
  hosts: localhost
  tasks:
  - name: Checking project list
    shell: |
      argocd proj list | grep xcore

    register: argoProj
  - debug: var=argoProj.stdout

  - name: create a project if not exits
    shell: |
      argocd proj create xcore
      # when: argoProj.stdout != "xcore"
    when: argoProj.stdout.find('xcore')!=-1

错误：

''
TASK [create a project if not exits] *****************************************************************************************
fatal: [localhost]: FAILED! => {"changed": true, "cmd": "argocd proj create xcore\n     \n# when: argoProj.stdout != \"xcore\"\n", "delta": "0:00:00.807940", "end": "2021-02-04 09:11:24.257123", "msg": "non-zero return code", "rc": 20, "start": "2021-02-04 09:11:23.449183", "stderr": "time=\"2021-02-04T09:11:24Z\" level=fatal msg=\"rpc error: code = InvalidArgument desc = existing project spec is different, use upsert flag to force update\"", "stderr_lines": ["time=\"2021-02-04T09:11:24Z\" level=fatal msg=\"rpc error: code = InvalidArgument desc = existing project spec is different, use upsert flag to force update\""], "stdout": "EE: 0/[]", "stdout_lines": ["EE: 0/[]"]}

注意:当已经创建了xcore项目时，我想跳过最后一个任务。当没有同名的项目时，需要执行最后一个任务。

shell命令的实际输出：

#argocd proj list | grep xcore
xcore                  gke_ec2nf-256816_us-central1_gke-devops,production  <none>                                           <none>                      <none>                        <none>          disabled
