NoMethodError, what does this mean?

Hello,

Im trying to update the php.ini file on my system. There's only two small changes
I want to make so I thought I would copy the file over to my templates directory and just add a couple variables in there to replace the values I want, and just overwrite the php.ini file. The only thing is I'm getting this error every time I try to apply the recipe.

Recipe: (chef-apply cookbook)::(chef-apply recipe)
  * template[/etc/php/7.2/apache2/php.ini] action create

    ================================================================================

I'm not sure what this means, and I literally can't find anything explaining it. Any feedback would be appreciated. (I'll post the recipe contents below)

template '/etc/php/7.2/apache2/php.ini' do
action :create
mode '0644'
source 'php.erb'
variables(
:post_size => '12M',
:upload_size => '10M'
)
end

The core problem here is the usage of chef-apply which is a limited subset that is primarily useful for toy examples and does not have feature parity with chef-client.

I'm just trying to run this on the local server to test it before I upload it to the chef server and run it on the nodes, but I still can't get it to work. Is there a specific way to pull an attribute from the default.rb with the recipe and apply it to a template? thanks in advance.

I've found this book online:
https://books.google.ca/books?id=fT1PAQAAQBAJ&pg=PA56&lpg=PA56&dq="undefined+method+'preferred_filename_on_disk_location'+for+nil:NilClass"&source=bl&ots=QXm5PfL8Gy&sig=ACfU3U1z-pUUMJyJIIbuq9Lm5Nri0-9Tnw&hl=en&sa=X&ved=2ahUKEwjB96uTjZniAhUineAKHRaKCSkQ6AEwB3oECAkQAQ#v=onepage&q="undefined%20method%20'preferred_filename_on_disk_location'%20for%20nil%3ANilClass"&f=false

It basically says to avoid using chef-apply when working with multiple ruby files and use chef-solo in order to apply the cookbooks/recipes. It says there is no way for the file to access the data in the template when using chef-apply.

It states this at the very top of page 61.
