Data masking for JSON response array

[ozanseymen]

Anybody know the data masking JSON path expression for a JSON array response like this:

[
  {
    "a": "b"
  }
]

I can't seem to mask any part of the response if the root is an array (rather than a plain object).

Here is the mock target I configured to test this: http://www.mocky.io/v2/59cd1f421100004e00ccca7e
