The error was: 'dict object' has no attribute - when I run ansible playbook for creating VM in proxmox

I am creating a Ansible Playbook to create VMs in Proxmox server. I need to create 2 VMs (VM1 & VM2) in proxmox, its attributes are stored in another file "list.yaml" and some defaults values are stored in "defaults.yaml". so I used loop condition to create the 2 VMS but I m getting a error as "The error was: 'dict object' has no attribute" (full error is mentioned below.

main Playbook.yaml

Error when i dry run the playbook:

TASK [Creating VMs] *****************************************************************
fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable.

PLAY RECAP **************************************************************************

anyone could figure out, what's wrong with the coding? and let me know how can i rectify it.

When you do

vars:
  list: '/vars/list.yaml'

this defines a string variable called list with the path of the list.yaml file as a value. It does not load what's in the file.

To do so you can change your dictionary to a list so that your list.yaml looks like this :

vms:
  - vm_id: "101"
    vm_name: "vm1"
    vm_cores: "2"
    vm_sockets: "1"
    vm_memory: "2048"
    vm_storage: "20G"
  - vm_id: "102"
    vm_name: "vm2"
    vm_cores: "2"
    vm_sockets: "1"
    vm_memory: "2048"
    vm_storage: "20G"

Then you can try with this playbook :

- name: 'Creating VMs in Proxmox'
  hosts: localhost
  vars_files:
     - /vars/list.yaml
     - /vars/defaults.yaml
  tasks:
  - name: 'Creating VMs'
    community.general.proxmox_kvm:
      api_user: "{{ user }}"
      api_password: "{{ passwd }}"
      api_host: "{{ host }}"
      node: "{{ node_name }}"
      vmid: "{{ item.vm_id }}"
      name: "{{ item.vm_name }}"
      vm_type: qemu
      ostype: l26
      disks:
        - size: "{{ item.vm_storage }}"
          type: sata
          storage: local-lvm
      bootdisk: sata
      cpu: "{{ item.vm_cores }}"
      sockets: "{{ item.vm_sockets }}"
      cpuunits: 1000
      cores: 1
      ballon: "{{ item.vm_memory }}"
      netif: '{"net0":"name=virtio,ip=dhcp,ip6=dhcp,bridge=vmbr1,rate=200"}'
      localtime: true
      state: present
    loop: "{{ vms }}"
