[chef] Re: debugging recipe for a specific incorrect file

[Tobias Unsleber < >]

Hi Nikhil,

try using pretty print to produce verbose output.
Check your objects if the contents are as expected.

# at recipe start
require 'pp'

insert after line 155

log pp host

Regards,
Tobias

I've fried my brain going thru each configs and I can't for the life of me figure out where i messed up the configs. Is there a way to debug this within the recipe? I've checked data bags and roles and it seems like the error is saying I have a null value as hostgroup, but I don't see anything.
