how to consume fiter:

- name: Get ALL backups using sedssion ID for app Name APP_NAME 
  uri:
    url: https://{{ INPUT_APPLIANCE }}/actifio/api/info/lsbackup?filtervalue=appname%3D{{ APP_NAME }}%26componenttype%3D0%26consistencydate%3C{{ INPUT_DATE }}%20{{ INPUT_TIME }}%26apptype%3DOracle%26jobclass%3Dsnapshot&sessionid={{ webpage.json.sessionid }}
    method: GET
    validate_certs: no
  register: get_all_backups

- debug: msg="object lenghth is {{  get_all_backups.json  | flifo_json() }}"
 
 you are passing an array and return array length
