Running chef solo worked, running second time gives me a ohai related error

I have 2 roles, base role has:

run_list “recipe[build-essential]”, “recipe[ohai]”, “recipe[runit]”,
“recipe[openssl]”, “recipe[git]”

webserver role has:

run_list “reciple[nginx]”

So running chef-solo the 1st time worked fine:

chef-solo -j chef.json -c config/solo.rb

Running it again (after 5 minutes) I get:

Why is it having issues locating my config/solo.rb file?

solo.rb has:

home_dir = File.expand_path(File.dirname(FILE) + “/…”)
file_cache_path home_dir
cookbook_path [ “#{home_dir}/cookbooks” ]
role_path “#{home_dir}/roles”
