Ansible is not creating RabbitMQ user using rabbitmq_user Module - rabbitmq

Question

I am trying to set up a rabbitMQ user using ansible's user management module.
Here is the code:
- rabbitmq_user:
user: "{{ rabbitmq_username }}"
password: "{{ rabbitmq_username }}"
vhost: /
configure_priv: .*
read_priv: .*
write_priv: .*
state: present
notify: restart rabbitmq
My application fails to authenticate using the above credentials to RabbitMQ. Also, the /etc/rabbitmq folder, which houses user configuration is empty.
Here is my complete task file which also installs rabbitMQ.
---
- include_role:
name: geerlingguy.rabbitmq
vars:
rabbitmq_version: "3.7.9"
rabbitmq_daemon: rabbitmq-server
rabbitmq_state: started
rabbitmq_enabled: true
- rabbitmq_user:
user: "{{ rabbitmq_username }}"
password: "{{ rabbitmq_username }}"
vhost: /
configure_priv: .*
read_priv: .*
write_priv: .*
state: present
notify: restart rabbitmq
- name: Enable RabbitMQ management console
command: rabbitmq-plugins enable rabbitmq_management
I can see that RabbitMQ is installed successfully and it starts but the user isn't created. I can't even authenticate to the Web UI using the above credentials.
Why is this happening and how to resolve this issue?

After much headache, I found the solution to be caused due to difference in the way Windows and Linux handle line endings.
The solution is detailed here.
I don't know why it was being caused in my ansible script, maybe it was due to my particular configuration of editor or something else. But this did solved my issue.
