Effected Components

domain_record

Expected Behavior

playbook runs every time without error nor changes (except the first time)

Actual Behavior

playout fails after the first run with error failed to create domain record: POST /v4/domains/[redacted]/records: [400] name: Record conflict - CNAMES must be unique

Steps to Reproduce

execute multiple times the following playbook

---
- name: Test linode.cloud.domain_record
  hosts: localhost
  become: false
  tasks:
    - name: Ensure CNAME record is aligned
      linode.cloud.domain_record:
        domain: example.com
        name: smtp
        type: CNAME
        target: mail.example.com.
        ttl_sec: 1800
        state: present

[macno]

looks like the problem is with the final dot in the target value:

target: mail.example.com.
