Filter multiple fields in only one JSONPath expression

Question

Given the following input JSON:

{
  "a": 1,
  "b": "some root string",
  "c":
  {
    "d": "some inner string"
  }
  "e": "ignored field"
}

Is it possible to obtain the following JSON using a JSONPath expression?

{
  "a": 1,
  "b": "some root string",
  "d": "some inner string"
}

Thank you in advance.

Below JsonPath should give you the expected output. However it depends on the type of Implementation.

$..['a','b','d']

You need to set the option Return null for missing leaf

It returns all the values without having to select any options.
