azure_rm Ansible plugin fails to parse dynamic inventory

I'm unable to create an Ansible dynamic inventory for Azure. I get the following error:

The inventory_azure_rm.yaml file is:

plugin: azure.azcollection.azure_rm
auth_source: credential_file
plain_host_names: yes
include_vm_resource_groups:
  - <redacted>
keyed_groups:
  - key: tags.applicationRole
    separator: ""

The ansible.cfg file is:

[defaults]
inventory = inventory_azure_rm.yaml

[inventory]
enable_plugins = host_list, script, auto, yaml, ini, toml

Ansible Azure collection version

bash-5.1# ansible-galaxy collection list

# /root/.ansible/collections/ansible_collections
Collection         Version
------------------ -------
azure.azcollection 1.11.0

I would appreciate any help on trying to solve this. Thank you.

Update:

• Fixed inventory_azure_rm.yaml file permissions.

  bash-5.1# ls -la inventory_azure_rm.yaml
  -rw-r--r--    1 root     root           200 Feb 24 17:27 inventory_azure_rm.yaml
  

• Updated the error stacktrace on the problem description running the command again.

Update2:

The Azure credentials file looks like this:

bash-5.1# cat ~/.azure/credentials
[default]
subscription_id=<redacted>
client_id=<redacted>
secret=<redacted>
tenant=<redacted>
cloud_environment=AzureCloud
