[Question]: Array from single item

[Dekeyras]

Hey,

Is there a way to output an array of one item from a single object?

Input Object:
{ email: "a@example.com" }

Required output:
{ emails: [ { email: "a@example.com" }] }

I have tried the below but its not quite what I need.

{
  "emails": {
    "path": "$empty",
    "nested": {
      "email": {
        "path": "email"
      }
    }
  }
}

Also this is invalid:

{
  "emails": [{
    "path": "$empty",
    "nested": {
      "email": {
        "path": "email"
      }
    }
  }]
}

This is an old question, but in case any else hits the same problem I had to do something similar and used a 'formatting' function to handle it:

"emails": {
    path: "email",
    formatting: (email) => {
        return [{ email }]
    }
}

"emails": {
path: "email",
formatting: (email) => {
return [{ email }]
}
}
This will cause an issue if there is a nested element for emails.
