The Problem

I managed to create a module that can't seem to find the type_of function, I have stdlib installed and when I try to run this branch of the module it consistently says it can't find the type_of function. I spent some time working with Reid Vandewiele and he tried cloning it down and he had the same issue on his own setup.

https://github.com/npwalker/puppetdb_gc/tree/cannot_find_type_of_function_error

Reid and I spent a few hours looking at it and trying some different things to determine a root cause and we couldn't narrow it down.

He recreated a small sample of just a module with a defined type that used the type_of function and that worked so we were at a loss for what the issue might be.

Reproduction

puppet module install puppetlabs/stdlib

cd /etc/puppetlabs/code/environments/production/modules

git clone https://github.com/npwalker/puppetdb_gc

cd puppetdb_gc

git checkout cannot_find_type_of_function_error

puppet apply -e "include puppetdb_gc"

The issue is occurring on PE 2016.4.2 which uses puppet-agent 1.7.1

More reproduction

I've also confirmed the issue using puppet-agent 1.8.1.

[root@agent-181-centos puppetdb_gc]# puppet apply -e "include puppetdb_gc"
