I am trying to use juniper_junos_facts from the Ansible Junos module to query some VM's that I provisioned using Vagrant. However I am getting the following error.

fatal: [r1]: FAILED! => "changed": false, "msg": "Unable to make a PyEZ connection: ConnectUnknownHostError(r1)"
fatal: [r2]: FAILED! => "changed": false, "msg": "Unable to make a PyEZ connection: ConnectUnknownHostError(r2)"

I see in the following document Here on juniper.net that this error occurs when you don't have the host defined correctly in the inventory file. I don't believe this to be an issue with my inventory file because when I run ansible-inventory --host all appears to be in order

~/vagrant-projects/junos$ ansible-inventory --host r1

 "ansible_ssh_host": "127.0.0.1", 
 "ansible_ssh_port": 2222, 
 "ansible_ssh_private_key_file": ".vagrant/machines/r1/virtualbox/private_key", 
 "ansible_ssh_user": "root"

~/vagrant-projects/junos$ ansible-inventory --host r2

 "ansible_ssh_host": "127.0.0.1", 
 "ansible_ssh_port": 2200, 
 "ansible_ssh_private_key_file": ".vagrant/machines/r2/virtualbox/private_key", 
 "ansible_ssh_user": "root"

My playbook is copied from the following document which I got from Here on juniper.net.

My Inventory File

[vsrx]
r1 ansible_ssh_host=127.0.0.1 ansible_ssh_port=2222 ansible_ssh_private_key_file=.vagrant/machines/r1/virtualbox/private_key
r2 ansible_ssh_host=127.0.0.1 ansible_ssh_port=2200 ansible_ssh_private_key_file=.vagrant/machines/r2/virtualbox/private_key

[vsrx:vars]
ansible_ssh_user=root

My Playbook

---
- name: show version
 hosts: vsrx
 roles:
 - Juniper.junos
 connection: local
 gather_facts: no

 tasks:
 - name: retrieve facts
 juniper_junos_facts:
 host: " inventory_hostname "
 savedir: " playbook_dir "
 - name: print version
 debug:
 var: junos.version

As you're using connection: local you need to give the module full connection details (usually packaged in a provider dictionary at the play level to reduce repetition):

 - name: retrieve facts
 juniper_junos_facts:
 host: " ansible_ssh_host "
 port: " ansible_ssh_port "
 user: " ansible_ssh_user "
 passwd: " ansible_ssh_pass "
 ssh_private_key_file: " ansible_ssh_private_key_file " 
 savedir: " playbook_dir "

Full docs are here (watch out for the correct role version in the URL): https://junos-ansible-modules.readthedocs.io/en/2.1.0/juniper_junos_facts.html where you can also see what the defaults are.

To fully explain the "provider" method, your playbook should look something like this:

---
- name: show version
 hosts: vsrx
 roles:
 - Juniper.junos
 connection: local
 gather_facts: no

 vars:
 connection_info:
 host: " ansible_ssh_host "
 port: " ansible_ssh_port "
 user: " ansible_ssh_user "
 passwd: " ansible_ssh_pass "
 ssh_private_key_file: " ansible_ssh_private_key_file " 

 tasks:
 - name: retrieve facts
 juniper_junos_facts:
 provider: " connection_info "
 savedir: " playbook_dir "
 - name: print version
 debug:
 var: junos.version
