python - django+celery+ansibleApi无返回

1.python调用AnsibleApi远程执行任务，不用celery的情况下能正确运行，使用的话返回为空.pdb调试发现是调用Ansible返回异常，但具体原因几天实在无法查出

2.代码复现如现如下：

tasks.py

from celery import shared_task
from .deploy_tomcat2 import django_process


@shared_task
def deploy(jira_num):
    #return 'hello world {0}'.format(jira_num)
    #rdb.set_trace()
    return django_process(jira_num)

deploy_tomcat2.py

from .AnsibleApi import CallApi

def django_process(jira_num):
    server = '10.10.10.30'
    name = 'abc'
    port = 11011
    code = 'efs'
    jdk = '1.12.13'
    jvm = 'xxxx'

    if str.isdigit(jira_num):
        # import pdb
        # pdb.set_trace()
        call = CallApi(server,name,port,code,jdk,jvm)
        return call.run_task()

复现方法
启动celery worker:
celery -A jira worker -Q queue.ops.deploy -n "deploy.%h" -l info
另一窗口生产消息:
deploy.apply_async(args=['150'], queue='queue.ops.deploy', routing_key='ops.deploy')
