Generate Separate UUID for JSON array of objects

[#1]

Hi All,

I am trying to generate separate UUID for JSON array of objects. I tried to use ${UUID()} in JOLT specification, but this is generating same UUID for all the elements.

e.g.

Input:

===============

{
  "aliases": [
    "Alias1",
    " Alias2"
   ]
}

JOLT Specification

=====================

[
{
"operation": "shift",
"spec": {
"aliases": {
"*": "alias[&0].name"
}
}
},
{
"operation": "modify-default-beta",
"spec": {
"alias": {
"*": {
"id": "${UUID()}"
}
}
}
}
]
Current Output:

=====================

"alias" : [ {
"name" : "Alias1",
"id" : "2948446b-6213-44ba-b81f-c4e5f7dab2eb"
}, {
"name" : " Alias2",
"id" : "2948446b-6213-44ba-b81f-c4e5f7dab2eb"
} ]

Any pointers will be greatly appreciated.

Thanks,

Hi @Biswa!
I tried various ways of getting a unique id for each array. Most of them failed. But, I tried to append the array index to the unique id. Even while doing it, I faced many issues. See if the below spec is okay

[
 {
  "operation": "shift",
  "spec": {
   "aliases": {
    "*": {
     "@0": "alias[&1].name",
     "$0": "alias[&1].id.${UUID()}-&1"
    }
   }
  }
 },
 {
  "operation": "shift",
  "spec": {
   "alias": {
    "*": {
     "id": {
      "*": {
       "$0": "alias[&3].id"
      }
     },
     "*": "alias[&1].&"
    }
   }
  }
 }
]
