I have a role which pushes updates to GitHub Enterprise. Every now and then the push fails, so I enclosed this push in a block/rescue with a rescue task to retry after a short random length pause. The result is success, mostly. However whenever the rescue task is triggered a later task in the playbook always fails and I’m scratching my head to understand why the later task fails.
The later task that fails is “Send success notification message via Email” and I’ve narrowed it down to the Jinja expression "{{ lookup('template','email_body_success.j2') }}". Both tasks are delegated to localhost. Other tasks that execute after the block/rescue also are delegated to localhost and they succeed.
Any ideas?

vars:
repo:
url: "git@{{ report_url.host }}:{{ report_url.org }}/{{ report_url.repo }}.git"
