exim-relay image pull failure

Playbook Configuration:

My vars.yml file looks like this:

---
    # The bare domain name which represents your Matrix identity.
    # Matrix user ids for your server will be of the form (`@user:<matrix-domain>`).
    #
    # Note: this playbook does not touch the server referenced here.
    # Installation happens on another server ("matrix.<matrix-domain>").
    #
    # If you've deployed using the wrong domain, you'll have to run the Uninstalling step,
    # because you can't change the Domain after deployment.
    #
    # Example value: example.com
    matrix_domain: mydoman.com

    # The Matrix homeserver software to install.
    # See:
    #  - `roles/custom/matrix-base/defaults/main.yml` for valid options

I run just update, then ansible-playbook -i inventory/hosts setup.yml --tags=install-all,ensure-matrix-users-created,start. I get this error at the very end.

Additional context
I used this guide

[spantaleev]

The error was: ModuleNotFoundError: No module named 'requests'

Your Ansible setup seems broken. It appears that the Python requests library is not available alongside Ansible.

I noticed that error so I installed it on my local and server machine but it throws the same error

I get a related error when running setup on newly installed Ubuntu 24.10 server. Again when trying to get Exim pulled. This is with the quick start set-up, nothing special. Seems the two are linked docker/docker-py#3256. This was fixed last year, so not sure why we're seeing these similar issues again.
