[BUG] - Ansible has problems with + in jinja2 templates to preserve new lines

[dimitrihof]

Describe the bug Role isn't running because of the following error

"msg": "AnsibleError: template error while templating string: expected token 'end of statement block', got '+'. String: #// include default config from upstream\ninclude \"/usr/share/bbb-apps-akka/conf/application.conf\"\n\n#// you can customize everything here. API endpoint and secret have to be changed\n#// This file will not be overridden by packages\nakka {\n  actor {\n    debug {\n      # enable DEBUG logging of all AutoReceiveMessages (Kill, PoisonPill et.c.)\n      autoreceive = {% if bbb_apps_akka_log_level == 'DEBUG' %}on{% else +%}off{% endif +%}\n      # enable DEBUG logging of actor lifecycle changes\n      lifecycle = {% if bbb_apps_akka_log_level == 'DEBUG' %}on{% else +%}off{% endif +%}\n    }\n  }\n  loggers = [\"akka.event.slf4j.Slf4jLogger\"]\n  loglevel = \"{{ bbb_apps_akka_log_level }}\"\n}\n\nservices {\n  bbbWebAPI=\"https://{{ bbb_hostname }}/bigbluebutton/api\"\n  sharedSecret=\"{{ bbb_secret }}\"\n}\n"
}

Expected behavior Run role as a whole without error.

so i found out that there is another way to achieve this https://github.com/ansible/ansible/issues/22531 Adding #jinja2: trim_blocks:False to the beginning of the template preservers new lines as well and keeps readability.

I don't know if thats a specific bug with my ansible version or if it's a general thing.

According to the issue in ansible adding + signs should be valid in jinja2, but i couldn't find anything about it in the documentation.

huh. I never had this issue but I guess this does not hurt anyone. 👍🏻

[BrutalBirdie]

@d3hof is this solved with PR #294
