You are passing a Hash as an parameter to a define.
Inside the define you expect the parameter to be of type String - according to 
what you do in the define.

You need to take care of splitting data accordingly in your define:
With Puppet 4 this is very easy to achieve:

define basket (
  Hash $arg,
){
  $arg.each |String $key, Hash $value| {
    file { “/tmp/${key}”:
      ensure => file,
      content => $value[‘arg’],
    }
  }
}

hth,
