Description
Getting the below error on AmazonLinux 2 with debug on. I ran the same code on Ubuntu 22.04LTS and AmazonLinux 2023 without any issues. Ansible version is 2.9.27. Python version is 2.7.18
The playbook variables I am using are:
- name: install node exporter
hosts: all
vars:
node_exporter_version: "1.8.2"
node_exporter_web_listen_address: "0.0.0.0:9100"
node_exporter_enabled_collectors:
- "systemd"
node_exporter_disabled_collectors: []
