Convert String array to JSON object array using JOLT

Question

Input :

[
  "link1",
  "link2"
]

Expected output:

[
  {
    "link": "link1"
  },
  {
    "link": "link2"
  }
]

I tried with multiple jolt spec without any luck. The closest one is:

[
  {
    "operation": "shift",
    "spec": {
      "*": {
        "#link": "[&1].link"
      }
    }
  }
]

You can use @ wildcard as looping through the array while assigning the desired key(link) on the right hand side such as

[
  {
    "operation": "shift",
    "spec": {
      "*": {
        "@": "[&1].link"
      }
    }
  }
]
