undefined method `map' for #<String: when using ['beaver']['files'] key

[muddman]

This is a great cookbook, thanks for providing it!

I need to override the default tags assigned to /var/log/syslog and /var/log/auth.log in an ubuntu environment but I am getting an error every time I try to use the ['beaver']['files'] key in either a Chef Role or, as in the case below, Opsworks custom json.

I am getting the error **"undefined method map' for #String:0x007f4a1a841dc0"** because map is not expecting a string, but ['beaver']['files']` has to be passed as a string in a role definition or custom json so I'm not sure how to override the default values without modifying the cookbook.

Environment

• Ubuntu 14.04
• Chef 11.10.4 running in AWS Opsworks
• Berksfile: cookbook 'beaver', '~> 1.5.0'

Chef Role / Opsworks Custom json

        }
    },

Error Output

When I run beaver::default I get the following error output

Am I using it incorrectly or do you have any thoughts on how I can override the defaults without changing the cookbook?

Thanks!
