Internal error when running basic Ansible playbook

[s.day]

I have a playbook to gather facts from cisco switches and routers.  The playbook works on the switch in my lab but fails with an internal error message on the router.  I have tried several other playbooks against the router and no matter what I'm trying to do I'm getting internal error.  I'm using Ansible version 2.9.19 python 3.

Playbook:

---
- name: "PLAY 1: Collect Device Facts"
  hosts: stage1
  tasks:
    - name: "P1T1: Gather Device Facts"
      ios_facts:

    - name: "P1T2: Write Device Facts"
      blockinfile:
        path: ./facts.yml
        create: yes
        block: |
          device_facts:
          {% for host in play_hosts %}
          {% set node = hostvars[host] %}
            {{ node.ansible_net_hostname }}:
              serial_number: {{ node.ansible_net_serialnum }}
              ios_version: {{ node.ansible_net_version }}
          {% endfor %}
          all_loopbacks:
          {% for host in play_hosts %}
          {% set node = hostvars[host] %}
          {% if node.ansible_net_interfaces is defined %}
          {% if node.ansible_net_interfaces.Loopback0 is defined %}
            - {{ node.ansible_net_interfaces.Loopback0.ipv4[0].address }}
          {% endif %}
          {% endif %}
          {% endfor %}
      run_once: yes
      delegate_to: localhost

Playbook output:

Hi

Is it failing for all routers on only some of them? Have you tried running just for few to validate?

Also, can you validate your ansible_connection is network_cli instead of local? (this change ansible_connection generates some common issues referenced on multiple thread on github if you search for that specific error)
