Hi,

I'm trying to build a playbook using set\_fact but the template seems  
to expand when I test locally on OSX but not when I invoke ansible via  
Jenkins on Linux. Here's the line:

&nbsp;&nbsp;&nbsp;&nbsp;- set\_fact:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;snapshot\_id: "production-snapshot-{{ 2000000000 | random |  
to\_uuid | replace('-', '') | truncate(12, end='') }}"

When I test this value gets set correctly to something like  
"production-snapshot-4d378e43eede". When I invoke this in Jenkins the  
value is "production-snapshot-". There's no other output or error  
message besides the truncated value.

Any idea what's going on here? Is this a bug?
