enabled_cops: all fails with NoMethodError

[russellshackleford]

When using the hardcore rubocop profile in .sync.yml, I get the following

pdk (FATAL): Failed to render template '.rubocop.yml.erb'
NoMethodError: undefined method `keys' for "all":String

.sync.yml:

.rubocop.yml:
  selected_profile: hardcore

I'm using tags/1.17.0-0-gd3a4319 on Ubuntu 18.04 with a new module that was created with pdk new module, then .sync.yml was created, followed by running pdk update.

I could reproduce this issue with the current version of the pdk-templates and PDK 1.18.1:

david@zion:~/tmp$ pdk new module hardcore --skip-interview
pdk (INFO): Creating new module: hardcore
pdk (INFO): Using the default template-url and template-ref.
pdk (INFO): Module 'hardcore' generated at path '/home/david/tmp/hardcore'.
pdk (INFO): In your module directory, add classes with the 'pdk new class' command.
david@zion:~/tmp$ cd hardcore/
david@zion:~/tmp/hardcore$ vi .sync.yml
david@zion:~/tmp/hardcore$ pdk update --force
pdk (FATAL): Failed to render template '.rubocop.yml.erb'
NoMethodError: undefined method `keys' for "all":String
david@zion:~/tmp/hardcore$ pdk --version
1.18.1
david@zion:~/tmp/hardcore$ cat .sync.yml 
---
.rubocop.yml:
  selected_profile: hardcore

david@zion:~/tmp/hardcore$

This is still a problem with latest released pdk and templates

  "pdk-version": "2.2.0",
  "template-url": "pdk-default#2.2.0",
  "template-ref": "tags/2.2.0-0-g2381db6"

The error displayed has changed slightly since the original report. Here is the output for selected_profile: off and selected_profile: hardcore (respectively):

$ pdk update
pdk (FATAL): Failed to render template '.rubocop.yml.erb'
NoMethodError: undefined method `[]' for nil:NilClass

$ pdk update
pdk (FATAL): Failed to render template '.rubocop.yml.erb'
NoMethodError: undefined method `&' for {}:Hash

The cleanups_only and strict profiles work.
