How to run ansible task based vaule count condition

I am trying to create one task based on the number of elements in a key.

my input will like below as json input

"srcaddr": "IP_192.168.10.10, IP_192.168.10.12"

or in array of json

"srcaddr": ['IP_192.168.10.10', 'IP_192.168.10.12']

  - name: ADD IPv4 IP ADDRESS GROUP
    chkr_fwobj_address:
      ipv4: "group"
      group_name: "ansibleIPv4Group1"
      group_members: "{{ srcaddr }}"
      adom: "{{ adom }}"
    when: "{{ srcaddr |length > 1}}"

I want to execute the above task when the count of the element is more than one, of it is more that one the task will create a group and add the members in to the group. if we have only one element then group creation task will be ignored

when condition should not be expanded. Correct syntax is

when: srcaddr|length > 1

The play below

- hosts: localhost
  vars:
    srcaddr1: ['IP_192.168.10.10']
    srcaddr2: ['IP_192.168.10.10', 'IP_192.168.10.12']
  tasks:
    - debug:
        msg: There is more then 1 address in the list srcaddr1.
      when: srcaddr1|length > 1
    - debug:
        msg: There is more then 1 address in the list srcaddr2.
      when: srcaddr2|length > 1

gives:

PLAY [localhost] *******************************************************

TASK [debug] ***********************************************************
skipping: [localhost]

TASK [debug] **********************************************************
ok: [localhost] => {
    "msg": "There is more than 1 address in the list srcaddr2."
}

PLAY RECAP *************************************************************
localhost                  : ok=1    changed=0    unreachable=0    failed=0

Note: The length of srcaddr: 'IP_192.168.10.10' is the length of the string. The length of srcaddr: [ 'IP_192.168.10.10' ] is the length of the list.
