Is this a warning that I can ignore? Environment: “ansible\_playbook\_python”: “/usr/bin/python3.12”, “ansible\_python.executable”: “/usr/bin/python3.12”, “ansible\_python\_version”: “3.12.8”, “ansible\_version.full”: “2.17.8” Main file: ```yaml --- - name: Test playbook hosts: localhost gather_facts: false tasks: - name: Importeer variabelen (Prod) ansible.builtin.include_vars: file: ./include.yml ``` include.yml: ```yaml varwithaq: test ``` This results in a warning ‘[WARNING]: Found variable using reserved name: q’ If I change the variable in the included file to ‘varwithanr’ no warning is printed. ---

This seems to be a bug in ansible-core 2.17.8. It does not happen in 2.17.7, or 2.18.0 (or `devel`, for that matter). It seems to have been introduced here: [fix warnings about reserved variable names to cover all sources (#844… · ansible/ansible@819e437 · GitHub](https://github.com/ansible/ansible/commit/819e437d967e33f7331cbc28e7d18920f7fa5740) ---

(It does happen with stable-2.18, I added a note here: [fix warnings about reserved variable names to cover all sources (#84432) by bcoca · Pull Request #84543 · ansible/ansible · GitHub](https://github.com/ansible/ansible/pull/84543#issuecomment-2636242869)) ---

Yep, but until the backports that were created today it was only fixed for `devel`, not for `stable-2.18` or `stable-2.17`. Now backports exist and the next 2.17.x and 2.18.x releases should not have this (anymore). ---

I’m running ansible [core 2.18.5] and see the follwing errors: ```auto [WARNING]: Found variable using reserved name: tags [WARNING]: Found variable using reserved name: serial ``` Coming from these variables: ```auto --- plugin: netbox.netbox.nb_inventory api_endpoint: https://netbox.com validate_certs: true config_context: false compose: netbox_device_tags: tags | default([]) | map(attribute='slug') netbox_serial: serial ``` I’m unsure if it’s `netbox_serial` that is the problem or `serial` coming from the Netbox Collection. ---

This is unrelated. Warnings about reserved names has been enabled for quite some time, the original message was a bug that would mark _any_ variable with a q as reserved, your message is about a specific variable name.
