Debugging recipe for a specific incorrect file

Chef Infra (archive)
1

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.

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
