I need to use replace to find a regexp that includes \n; however, I keep
getting an error. How can I properly do this (don't even know if I am
using back reference correct either, but if I can get past this error I
think I can figure that part out)?
Thanks in advance!

# DNS Update For Ubuntu 18
- name: Update DNS servers
replace:
path: /etc/netplan/50-cloud-init.yaml
regexp: ".*nameservers.*$\n.*addresses:(.*$)"
replace: "\1 {{ dns1 }}, {{ dns 2}}"
notify: "{{ handler_name }}"
Error:
TASK [dns_update : include_tasks]
********************************************************************************************************************************************************************************************************
fatal: [ansible-ub18]: FAILED! => {"reason": "Syntax Error while loading
YAML.\n found unknown escape character\n\nThe error appears to have been
in '/etc/ansible/role/dns_update/tasks/Ubuntu18.yml': line 7, column 15,
but may\nbe elsewhere in the file depending on the exact syntax
problem.\n\nThe offending line appears to be:\n\n regexp:
\".*nameservers.*$[\\n].*addresses:(.*$)\"\n replace: \"\\1 {{ dns1 }},
{{ dns 2}}\"\n ^ here\nWe could be wrong, but this one looks
like it might be an issue with\nmissing quotes. Always quote template
expression brackets when they\nstart a value. For instance:\n\n
with_items:\n - {{ foo }}\n\nShould be written as:\n\n
with_items:\n - \"{{ foo }}\"\n"}
