ansible playbook is failing

Question

part of playbook is given below:This is the ansible playbook(main.yml)

         - name: setting Info data
           set_fact:
             application_data:
                log_file_name: "{{ log_file_name }}"
                log_file_dir: "{{ log_file_dir }}"

         - name: call application
           custom_application:
               verb: 'call'
               body: "{{ application_data }}"
           register: activate_output

custom_application.py:

this is the custom ansible application getting called from main.yml file.

 ###couple of imports


        def main():
            fields = {
                "verb": {"required": True, "type": "str"},
                "body": {"required": True, "type": "str"},

            }
            module = AnsibleModule(argument_spec=fields)
            verb = module.params['verb']
            body = yaml.load(module.params['body'])
            application = application()   
            response = application.call(body)
            module.exit_json(changed=True, meta=response)

        if __name__ == '__main__':
            main() 

Application.py: python class that does couple of application related things.

def call(body):
   application = {}
   application["is_activated"]=True
   return application

above the main.yaml and custom ansible module and application class

        fatal: [localhost]: FAILED! => {
            "changed": false,
            "failed": true,
            "module_stderr": "",
            "module_stdout": "\"changed\": true, \"meta\": {\"is_activated\": true}}\n",
            "msg": "MODULE FAILURE",
            "rc": 0
        }

Module_stdout is as below:

module stdout i truncated the exact module_stdout is given below:

{
    "changed": false,
    "failed": true,
    "module_stderr": "",
    "module_stdout": "{
           \"invocation\": {
               \"module_args\": {
                     \"body\": \"{
                       'application_id': '3f17f2a3-0510-457d-a164-72f3a71c6455', 
                       'file_path': '/tmp/vishnu.json', 
                       'log_file_name': '42ae1299-9cbf-49d3-82da-d2d1eb108eef-2017-09-09-11:26:03.log', 
                       'log_file_dir': '/home/oracle/logs/oracle/'
                      }\",
                      \"verb\": \"activate\"
                  }
              }, 
          \"changed\": false, 
          \"meta\": {
             \"is_activated\": true}
     }\n",
    "msg": "MODULE FAILURE",
    "rc": 0
}

and i think its a valid json object.

a particular ansible step is failing as shown above with no stderr. and i am also getting warning as above.. let me know where i went wrong

Note: i am sending json data as the output of custom ansible module as well

Answer 1

From module_stdout you can see that the opening { is missing, giving you invalid JSON object, thus module is failing.

Check that your application doesn't mess with standard output.
