cisco.nxos.nxos_lag_interfaces KeyError in overridden state

[clammers]

SUMMARY

We're trying to run the following playbook on a nxos 9000v where no port-channel exists. So we first create a interface "port-channel99" and then running the nxos_lag_interfaces for configuring the corresponding interface. The main problem we're struggling with is the "overridden" state cause the playbook fails with

"/var/folders/np/d5pmgqdj1q9_spgdts9h5hmm0000gn/T/ansible_nxos_lag_interfaces_payload_zHpOoI/ansible_nxos_lag_interfaces_payload.zip/ansible_collections/cisco/nxos/plugins/module_utils/network/nxos/config/lag_interfaces/lag_interfaces.py", line 202, in _state_overridden
KeyError: 'members'

STEPS TO REPRODUCE

Run the following playbook on a switch where no PortChannel exists

- hosts:
    <nxos-switch>
  check_mode: no
  gather_facts: no
  # 'never' used to prevent a task to run unless a tag is specified
  tasks:

    - name: Port-Channel Layer 2 Configuration
      nxos_interfaces:
        config:
        - name: port-channel99
          description: Ansible Resource LAG

    - name: Port-Channel LAG Configuration
      nxos_lag_interfaces:
        config:
        - name: port-channel99
          members:
          - member: Ethernet1/9
            mode: active
            force: yes
        state: overridden

EXPECTED RESULTS

Correctly configure Port-Channel99

ACTUAL RESULTS

Seems to be an problem in source

    def _state_overridden(self, want, have):
        """ The command generator when state is overridden

        :rtype: A list
        :returns: the commands necessary to migrate the current configuration
                  to the desired configuration
        """
        commands = []
        for h in have:
            obj_in_want = search_obj_in_list(h["name"], want, "name")
            if obj_in_want:
                diff = self.diff_list_of_dicts(
                    h["members"], obj_in_want["members"]
                )
                if not diff:
                    continue
            commands.extend(self.del_all_commands(h))
        for w in want:
            commands.extend(self.set_commands(w, have))
        return commands

and cause there is no really configured Port-Channel (only just the interface) h["members"] is the KeyError

This will fix the issue:

                diff = self.diff_list_of_dicts(
                    h.get('members', []), obj_in_want["members"]
                )
