Bug #14979: inconsistent server 400 error: undefined method `parent' for 
nil:NilClass
https://projects.puppetlabs.com/issues/14979#change-69760

Author: Banio Carpenter
Status: Investigating
Priority: Normal

Category: 
Target version: 
Affected Puppet version: 
Keywords: 
Branch: 


I see this server 400 error intermittently when run as a cron. I'm not able to 
reproduce it running puppet manually. I have tried many times to reproduce it 
using:

    puppetd -t
    puppet agent -t
    puppet agent --no-daemonize --onetime --verbose
    puppetd --no-daemonize --onetime --verbose

The error is:

    Could not retrieve catalog from remote server: Error 400 on SERVER: Failed 
to parse template admissions/zz_admissions_vhost.conf.erb: undefined method 
`parent' for nil:NilClass at 
/etc/puppet/modules/admissions/manifests/apache.pp:84 on node nodee.mydomain.com

the relevant part of apache.pp (content is line 84):

    file { "/etc/httpd/conf.d/zz_admissions_vhost.conf":
    ensure => present,
    owner => root,
    group => root,
    mode => 640,
    content => template('admissions/zz_admissions_vhost.conf.erb'),
    } ->


the only fact/variable I have in the template 
(admissions/zz_admissions_vhost.conf.erb) is this:

    ServerName <%= domain %>

Versions:

    # puppetd --version
    2.7.14
    # ruby --version
    ruby 1.8.5 (2006-08-25) [i386-linux]
    # facter --version
    1.6.9

Again I can't reproduce this manually, only happens when run as a cron, and 
even then only sometimes--percentage ranges from 10% to 75% depending on the 
day.  The cron is:

    puppet agent --no-daemonize --onetime --verbose
