Key Field includes Unwanted Double Quotes

[aldredb]

Hello, tried the new-orders example. I the consumed the events and printed the keys. I noticed the key field includes the double quote, which is not correct. Tried different expressions such as "#{Internet.uuid}", same issue

{
  partition: 0,
  key: '"1391037731"',
  offset: '0',
  value: '{"favorite_beer":"Sublimely Self-Righteous Ale","gender":"Female","name":"Ruben Miller","state":"Maryland"}'
}
