rabbitmq installation failed because of 'nothing provides socat needed by rabbitmq-server' - centos8

[pamtrak06]

I try to install RabbitMQ on a Centos8 VM. But it fails. Here the called roles in my playbook

- { role: rockandska.erlang, become: yes }
- { role: rabbitmq.deps, become: yes } # install socat and logrotate => https://github.com/rabbitmq/chef-cookbook/issues/355
- { role: geerlingguy.repo-epel, become: yes }
- { role: geerlingguy.rabbitmq, become: yes }

The issue

# TASK [geerlingguy.rabbitmq : Ensure RabbitMQ is installed.] ********************
# fatal: [nnbus]: FAILED! => {"changed": false, "failures": [], "msg": "Depsolve Error occured: \n Problem: conflicting requests\n  - nothing provides socat needed by rabbitmq-server-3.8.3-1.el8.noarch", "rc": 1, "results": []}
# [nnbus] TASK: geerlingguy.rabbitmq : Ensure RabbitMQ is installed. (debug)> User interrupted execution
# ERROR: Job failed: exit code 1

The concerned code ?

- name: Ensure RabbitMQ is installed.
  yum:
    name: "/tmp/{{ rabbitmq_rpm }}"
    state: "present"
