jinja[invalid] when using a variable to feed the seed parameter of ansible.builtin.random

[snail59]

Summary

The "idempotent method to generate unique hashes per system is to use a salt that is consistent between runs"
found here: https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_filters.html#hashing-and-encrypting-strings-and-passwords works as expected.
But ansible-lint returns an error : The only supported seed types are: None, int, float, str, bytes, and bytearray.

Issue Type

• Bug Report

OS / ENVIRONMENT

ansible-lint 6.20.0 using ansible-core:2.15.4 ansible-compat:4.1.10 ruamel-yaml:0.17.32 ruamel-yaml-clib:0.2.7

(I tried with version 6.18 and 6.17.1 too)

• ansible installation method: OS package
• ansible-lint installation method: OS package

STEPS TO REPRODUCE

run the following playbook.

- name: Demo
  hosts: localhost
  gather_facts: false
  tasks:
    - name: Use seed in random
      ansible.builtin.debug:
        msg: "{{ 65534 | ansible.builtin.random(seed=inventory_hostname) }}"

Desired Behavior

I hoped for this code to pass.

Actual Behavior

• the output of running ansible-playbook including the command line used:

ansible-playbook test.yml
