"Deploy cron script" task treats “dest” as a directory instead of as a file and fails

[raneq]

I suspect this will be a "works for me", but maybe you can help me out. I have posted a question to stack overflow

What ansible-restic should do here is to deploy a cron script based on a template, with name restic-backups-test, inside directory /etc/cron.d/ . However, it looks like ansible interprets that the directory should be /etc/cron.d/restic-backups-test and the file name just the epoch timestamp like 1551799877
I'm afraid it has to do with my environment instead, but I don't know what could make ansible change this behaviour, and my playbook doesn't do black magic.

What's the value of your restic_repos variable?

I was wrong on the stackoverflow question, restic_repos contained a slash!!
Thank you a lot. If you want to take credit on stackoverflow, I will aprove your answer.
I don't know if it is usual to set variable names with special characters like that, in my case, was due a misunderstanding.
