{
    "Hello": "World",
    "" : "This is an empty key",
    "some_key": {"": "bad data here", "ok": "I am ok"},
    "some_array": [{"": "bad data here", "ok": "I am ok"},{"ok": "I am just ok"}]

}

With fix nothing()

Results in:

{
  "Hello" : "World",
  "" : "This is an empty key",
  "some_key" : {
    "some_key" : "bad data here",
    "ok" : "I am ok"
  },
  "some_array" : [ {
    "1" : "bad data here",
    "ok" : "I am ok"
  }, {
    "ok" : "I am just ok"
  } ]
}

Should be:

{
  "Hello" : "World",
  "" : "This is an empty key",
  "some_key" : {
    "" : "bad data here",
    "ok" : "I am ok"
  },
  "some_array" : [ {
    "" : "bad data here",
    "ok" : "I am ok"
  }, {
    "ok" : "I am just ok"
  } ]
}
