Error

The icingaweb2 ini configuration fails with the following error

failed: [icingawebhost] (item=config) => {
  "ansible_loop_var": "item", 
  "changed": false, 
  "item": "config", 
  "msg": "AnsibleError: Unexpected templating type error occurred on ({% import 'ini_template.j2' as ini_template %}\n{{ ini_template.generate_ini(_i2_config_hash) -}}\n): sequence item 5: expected str instance, int found. sequence item 5: expected str instance, int found"
}

Cause

The problem is in roles/icingaweb2/templates/ini_template.j2 line 7

{% if value is number %}
{{ option }} = "{{ value }}"

Solution

casting the value to a string fixes the problem

{% if value is number %}
{{ option }} = "{{ value | string }}"
