How prevent chef failure on ruby code?

Sometimes Chef fails on the next code (this code not in block or any resource):

tmp = title.force_encoding("ISO-8859-1").encode("UTF-8")
title = tmp.encode('ISO8859-1').force_encoding('UTF-8')

error that I get:

NoMethodError

undefined method `force_encoding' for nil:NilClass

My question is how best practice to ignore any code error and to continue to run rest recipes, thanks

Solution

You didn't show where title comes from so they best I can say is to put your code in a ruby_block resource and use the ignore_failure property. You can also use normal Ruby rescue blocks for imperative code but be aware of how that interacts (or rather, doesn't) with resources, see https://coderanger.net/two-pass/ for some details on the loading process Chef uses.
