Can not use variables in tag names when using amazon.aws.ec2_tag

[finnje]

SUMMARY

When using the module: ec2_tag variables within the "key" (tag name) aren't populated. It creates a tag with the name and actually adds {{ VARIABLE_NAME }} to the tag. The value side lookups work fine, just not the name.

  connection:   local
  gather_facts: false

  collections:

  vars:
    SUBNET:    subnet-**********
    TAG_KEY:   color
    TAG_VALUE: blue

  tasks:

    - name: aws    | add tag to resource
      amazon.aws.ec2_tag:
        resource: '{{ SUBNET }}'
        state:    present
        tags:
          '{{ TAG_KEY }}': '{{ TAG_VALUE }}'
      register: tag_result
